The experiment were performed according to the L₉ orthogonal design matrix on the lathe machine. The result shows that optimal condition of the parameters gives surface finish which is better than initial . The cylindrical turning is a popular metal cutting prceses used in the indusrties to removed unwanted material in desired workpiece material.

ABSTRACT Filler material choice for repair welding of stop valve spindle of thermal power plant by-pass pipeline was presented in this paper. Repair welding of the stop valve spindle was necessary because of plant operating problems due to very frequent localized damage appearance in the form of erosive wear on it. For this purpose it was necessary to choice appropriate filler material with high wear resistance characteristic. Experimental investigation and testing (hardness measurement, chemical composition analysis and microstructural investigation) of prepared specimens after welding simulation with different kind of filler material was performed. On the basis of obtained results it was recommended procedure for application of the filler material with generally preferable characteristic.

The logistics system is an important and stimulating process for producers. The logistics system starts with the supply of raw materials, product design, assembly and distribution to customers. A supply chain can be considered when designing this process. Therefore, modelling and optimizing supply networks related to the different processes of the logistics system and data transactions is a major challenge. On the other hand, developments in the digital environment of logistics systems are integrated with the development of Industry 4.0, including Internet of Things (IoT), big data, cloud computing and information systems. Therefore, this document discusses the development of information systems on different processes of logistics systems in modelling the exchange of data between elements of the supply network. The concepts of big data and cloud computing are taken into account when proposing information flow mechanisms. The result allows a complete exchange of data between the elements of the intelligent logistics system on the Internet platform. The functions and solutions of sales, transport, inventory and sales are presented in the different phases of the proposed logistics system. The need for data flow is created using a database concept for making real-time decisions

This research work investigated the influence of the graphite powder on the Mechanical behaviour of Aluminium 7075/Graphite Powder(Gr)/Bagasse Ash(BA) hybrid composite. This investigation reveals the effectiveness of incorporation of graphite powder in the composite for gaining enhancing mechanical properties. The Al7075 (Aluminium alloy 7075) reinforced with bagasse ash and graphite powder to form MMCs were investigated. The conventional liquid casting technique was used for the fabrication of the composite material and subject to T6 heat treatment. The composite was produced for different percentages of graphite powder and bagasse ash. The specimens were prepared as per ASTM standard size by turning and facing operations to conduct tensile tests, compression tests and hardness tests. The specimens for tensile and compression strength are tested using universal testing machine and for hardness they are tested using Brinell hardness testing machine. The reinforcement content was chosen as 2,4, 6wt.% of Graphite powder to identify its potential for self lubricating property under dry sliding conditions. Through the results, it is concluded that the MMC obtained has got better tensile strength, compression strength, yield strength and hardness properties when compared to non-heat-treated Al 7075 alone.

The article discusses the review of the state of professional competence art, presenting a compilation of indexed research in the two most comprehensive multidisciplinary databases: "Scopus" and "Web of Science" from 1950 to 2012. By analyzing scientific domain of research literature the existence of eight approaches of professional competence is shown, some related to the corresponding international system of competence certification which are supported by different philosophies with a common base. These theoretical and visually positions presented are compared with each other and serve to approach the competence analysis for higher education in engineering. From the presented approaches, it is emphasized that the holistic approach is the most appropriate for coding competence for higher education in engineering. In the analysis of competence in engineering the Tuning Project in Latin America is described and two competence encodings are presented: CDIO and IPMA, both are compared to the Tuning Project for Latin America in order to answer the question of what would be the most useful to cover professional competence needs in Engineering in Latin America.

Modern vehicles are much safer, lighter, faster and drive convenient as far as older vehicles are concerned. They are more stable and having better safety features. Now a days everyone is giving more importance to the passenger safety. In order to avoid the passenger threats during vehicle crash, we need to understand the collusion effects on vehicle body and passenger cabin. It can be studied well with the help of crash test where vehicle is allowed to hit an obstacle with a particular speed and due to hitting vehicle damage and effect of collusion on the cabin is observed. But physical crash test is much costlier and consumes money, effort, material and much more things. To avoid this virtual crash test is preferred in industry. It is a simple computerised crash test simulating process in which virtual model of vehicle is allowed to hit a virtual obstacle with a known speed virtually on computer. The effects will be generated by finite element analysis module in the form of deformation and stresses on virtual parts. It also shows the bending and cracks on parts. Hence this virtual crash test is Having 95 % accurate results. It also avoids physical damage on vehicle, saves efforts and money. In this paper we have studied the various literatures available based on this crash test. Authors opinions are understood and based on their opinions a standard conclusion is drawn. This study will help to conduct virtual crash test with the help of FEA package and CAD Tool.

By using the method of finite elements and starting with the possibilities given by the program system ANSYS in the field of application, research has been performed regarding the analysis of static behavior of a centrifugal pump shaft. The computational analysis of static behavior of shaft using the method of finite elements on the examined model during the phase of projecting, was aiming for a timely sighting of critical spots, in order to avoid possible further malfunction. In this way it is possible to examine validity of the basic solution with no need for making the prototypes. By static behavior analysis, in other words, using the method of finite elements it was shown to which extent can certain conditions of exploitation, created tensions, that is shifted knots, cause difficulties in the whole model performance. Analysis of the static behavior of shaft was performed for two cases with different load: the effect of radial force and the torsion moment. A special attention was...

Most of the marine propellers are made of metal material such as bronze or steel. The advantages of replacing metal with CFRP composite materials are that the latter is lighter and corrosion-resistant. Another important advantage is that the deformation of the composite propeller can be controlled to improve its performance. Propellers always rotate at a constant velocity that maximizes the efficiency of the engine. When the ship sails at the designed speed, the inflow angle is close to its pitch angle. When the ship sails at a lower speed, the inflow angle is smaller. Hence, the pressure on the propeller increases as the ship speed decreases. The propulsion efficiency is also low when the inflow angle is far from the pitch angle. If the pitch angle can be reduced when the inflow angle is low, then the efficiency of the propeller can be improved. In addition the load-bearing fibers can be aligned and stacked to reduce fluttering and to improve the hydrodynamic efficiency. Composites can offer the potential benefits of reduced corrosion and cavitations damage, improved fatigue performance, lower noise, improved material damping properties, and reduced lifetime maintenance cost. Traditionally marine propellers are made of manganese-nickel-aluminum-bronze (MAB) or nickel-aluminum-bronze (NAB) for superior corrosion resistance, high-yield strength, reliability, and affordability.

A detailed study was carried out on crankshafts used in two wheeler made from C45 (EN 8/AISI 1042) steel. Undesirable noise was heard in crankshaft when the engine is in running. This was stated as failure of crankshaft. Material has been peeled off and seemed to be scraped at the central portion of the crankpin.  It was the bearing seating place where oil hole also provided. Under analysis the crankpin was identified as tempered. Chemical composition, micro-hardness and microstructure were studied and compared with the specified properties of the crankpin material. Reason for failure is identified as wear due to lower hardness, improper lubrication and high operating oil temperature.

Wear is produced when two elements press against each other, such as apron liner, blow bars and crushing material. During this process, small materials from each element become detached, causing the surface to wear away. A primary factor in wear for crushing applications is abrasion. The blow bars on the rotor of an impact crusher wears faster because of the impact and rubbing with material during crushing. This contributes to about 60 % of the cost of wear parts in an impact crusher. This study is focus on wear analysis of rotor blow bars of a compound impact crusher used in limestone crushing. The wear rate on the blow bars were calculated using the measured length of the blow bar before and after crushing 100,000 tons of limestone. The blow bars are refilled and hard-faced to prolong it life span. However, wear analysis shows high wear toward the centre of the blow bar and this can be attributed to non-uniform feeding of the crusher. The wear rate was found to be 0.000160, at point A and E, 0.000172, at point B and D and 0.000194 mm/ton at point C. The blow bars wearing is due to trickle feed which gives uneven and excessive wear at the centre and reduces the life of the blow bar. The material feed rate was adjusted and uniform feed was maintained through the entire length of the blow bar. Rotor speed was checked and adjusted, cleaning was intensified in the chamberand discharge gap setting was adjusted to 50 mm. The wear on blow bar decreases to 0.000114 mm/ton of limestone crushed after the intervention with uniform and gentle radius profile on the blow bar.

Torsion bar suspension is commonly used on tracked vehicles, although there are some wheel driven vehicles using this type of suspension. The suspension works by having one end of the bar fixed in position on the vehicle chassis to prevent rotation, whilst the other end is connected to a control arm and wheel hub. The control arm is fixed to the chassis using rubber bushings which allow only vertical movement about the mounting points. The torsion bar is connected to the control arm through a number of splines which translate the vertical movement of the control arm into a rotational or torsional force. This paper tries to give an idea about the previous researches & their finding about study of Torsion Bar, Static analysis (FEA) of torsion bar and study related applications of composite materials.

Many engineering machines and mechanical components are subjected to fluctuating stresses, taking place at relatively high frequencies and under these conditions failure is found to occur. This is called fatigue failure. And this led to the invention of a fatigue testing machine. In view of effective design that will not fail accidentally, this research is conceived. This testing machine will determine the strength of materials under the action of fatigue load. Specimens are subjected to repeated varying forces or fluctuating loading of specific magnitude while the no. of cycles are counted till the breakage of specimen and results are plotted.

Agriculture vehicles and farming equipment like tractors and Tillers, Sprayers etc., also use a similar automobile transmission. With the shortage in labor and also increase in labor expenses there is a trend to automate the farming equipment to save time and labor cost. The major challenges in automation is the clutch control which is presently manual, and the automatic clutch control in the high end vehicles cannot be used due to the high cost, complexity of design. Hence in order to carry out the automatic clutch control a special electro mechanical clutch is needed. The fully- automatic electromechanical Single plate clutch for autonomous agriculture spray vehicle is our attempt to design develop and apply the clutch to agriculture automation. The Clutch development includes the theoretical design as to the Power and torque transmission of the engine power and also design of an innovation clutch engagement-disengagement arrangement with quick-response, low cost, easy serviceability and compact space. The paper presents a brief overview of the clutch, design and analysis of the critical components like the flywheel, clutch plate and pressure plate, The components have been developed using Unigraphic Nx8 and the structural analysis has being done using Ansys Workbench 16.0 . The testing was carried out on the clutch using a test rig to determine the performance characteristic of the clutch.

For Pre-Processing used MSC PATRAN and MSC NASTRAN for solving followed by Fatigue calculations.

There is an increasing interest in development of bio-composite materials and their applications in various fields, to replace synthetic fiber reinforced composites. In this study, mechanical properties such as tensile characteristics, flexural characteristics, and compressive characteristics of hardwood sawdust (HSD) and oil bean pod shell (OBPS) hybrid composites in epoxy (EP) matrix were investigated as a function of filler loading. Hybridized composite sample was prepared with 20, 30, 40, 50, and 60% reinforcements of sawdust and oil bean pod shell particulate (the fillers) in the ratio of 1:1 and cured for 21 days. The prepared composites were tested according to ASTM standards, and the results showed that the filler reinforcement had strong effect on the tensile, compressive and flexural characteristics of the composite board. The tensile strength, transverse rupture strength, Bending Modulus and compressive strength increased progressively up to 50 % filler loading, before their values dropped at 60 % filler loading; while percentage elongation at fracture only increased to 40 % before it started decreasing. The results of this study showed that composite could be successfully developed using HSD, OBPS and epoxy would be a substitute for wood-based material in many applications.

In Recent days the less weight composite materials are majorly used in engineering applications. The composite materials have enough characteristics of resisting tribological properties, hardness and tensile strength. Due to lesser weight and strength, a composite material plays a major role in emerging engineering applications. Aluminium LM5 has been used as matrix material and different weight percentage of fly ash (10%, 20%, and 25%). The mechanical behaviour and microstructure of Al-Flyash composites are evaluated. Magnesium is added to reduce the surface tension and avoids the neglecting of the particles from the melt. In this article we are suggest fly ash composite material gives better efficiency in automotive applications and reducing the tribological properties.

Over-pressure can impact weak points in a hydraulic system, which in turn can result in the mechanical failure of the individual system components. Over-pressure also tends to increase the burden on the lubricated surfaces causing abrasion and even catastrophic system failure. Therefore, the working pressure must remain within the safe value. This function can be achieved by using a pressure relief valve (PRV) or a pressure safety valve (PSV). A PRV/PSV provides an alternative path for the fluid to flow back into the reservoir, when no flow can be directed to the working parts of the system. Hope you enjoy reading further. Please, go ahead… PSV Vs PRV A PSV is designed to open completely when the set pressure is reached. However, it does not close automatically after the fluid discharge. A PRV modulates the flow through the system to keep its working pressure at the preset level. It is designed to re-close after the normal pressure condition has been restored. Types of (PRVs) A direct-acting PRV is regarded as a conventional type valve in which the valve opening is directly controlled by the

The aim is to improve the reliability of the evaporator by some technical modifications. Here it was observed that the reliability of evaporator is much more affected on the performance of evaporative coil. Hence to improve the reliability of evaporator, the concept of parallel redundancy is applied for evaporative coil. A system dynamic modeling of these modified systems projects a clear picture for the performance of evaporator for next fifteen years of its working[2].

Now days we tend to see pedal operated tools are helpful in day to day life. In this paper we target the planning of pedal operated butter churner that will be helpful and cheap to normal milkman. This will assist to extend the productivity of worker in rural area. Many devises are available in the market for production butter for large quantity at the same time domestic mixer may be use for very low quantity and it also required electric power. Current manual process of developing butter is the long, taking several hours to complete and needs most physical efforts. The demand of butter is increases day by day. In order to meet this demand a more robust mechanism is required. This project seeks to develop butter by means that of combination using bicycle & mechanism.

Cycloid drives are a relatively new group of planetary power transmissions. These transmissions have numerous favorable characteristics, such as a wide range of transmission ratios, very compact design, high reliability in dynamic exploitation conditions, high efficiency, etc. As they are part of a newer generation of transmissions , the possibility of using other materials other than steel in their production is not yet fully investigated. For the purposes of this investigation a single stage cycloid reducer was designed and manufactured out of mainly plastic components. The theoretical efficiency was determined and experimentally tested. Their comparative analysis is given through the discussion. The paper concludes with suggestions for further research on this type of cycloid reducers.

— In the industry, for movement of material from point to point, material handling equipment is necessary. Material handling equipment transports, transfers, moves the material to the desired destination. Roller conveyor is the material handling equipment used to transfer the material over a fixed path. Components of powered roller conveyors are shaft/Axle, rollers, frame, chain, selection of bearing etc. It designed on the basis of load carring capacity, distance to be moved, velocity etc. In this project the present powered roller conveyor, the rollers deflect to the design loading. The excessive deflection and its corresponding reactions are transmitted to the bearings. This work is undertaken to do the analysis and optimization of powered roller conveyor using FEA. In this project stress analysis of existing system is carried out analytically and by using FEA. The geometrical modifications suggested to avoid its deflection. In the present work, an attempt is made also of the reduction in weight of existing roller conveyor by optimizing the critical parts of (e.g. inner & outer diameter of roller, thickness of roller) conveyor without affecting functional performance. Optimization gives optimum design for same loading condition with large weight reduction.

Crankshaft is one of the critical components of an IC engine, failure of which may result in disaster and makes engine useless unless costly repair performed. It possesses intricate geometry and while operation experiences complex loading pattern. In IC engines, the transient load of cylinder gas pressure is transmitted to crankshaft through connecting rod, which is dynamic in nature with respect to magnitude and direction. However, the piston along with connecting rod and crankshaft illustrate respective reciprocating and rotating system of components. the dynamic load and rotating system exerts repeated bending and shear stress due to torsion, which are common stresses acting on crankshaft and mostly responsible for crankshaft fatigue failure. Hence, fatigue strength and life assessment plays an important role in crankshaft development considering its safety and reliable operation. The present paper is based on comparative studies of two crankshafts of fatigue life assessment of a single cylinder diesel engine crankshaft by using High cycle fatigue (HCF) technique

Earth-air heat exchangers, also called ground tube heat exchangers, are an interesting technique to reduce energy consumption in a building.They can cool or heat the ventilation air, using cold or heat accumulated in the soil. Several papers have been published in which a design method is described. Most of them are based on a discretisation of the one-dimensional heat transfer problem in the tube. Three-dimensional complex models, solving conduction and moisture transport in the soil are also found. These methods are of high complexity and often not ready for use by designers. The temperature of earth at a certain depth about 2 to 3m the temperature of ground remains nearly constant throughout the year. This constant temperature is called the undisturbed temperature of earth which remains higher than the outside temperature in winter and lower than the outside temperature in summer. When ambient air is drawn through buried pipes, the air is cooled in summer and heated in winter, before it is used for ventilation. The earth air heat exchanger can fulfill in both purpose heating in winter and cooling in summer.

Among all the metal industries, the iron and steel industries are the most energy intensive sectors in India. Worldwide the use of induction furnaces in steel industries especially in foundries has increased exponentially. A great deal of research is dedicated to identify the factors that affect the performance of the furnace. It is observed that quantity of molten metal produced per batch, average time required for production per batch, electricity consumption per ton ,raw material in ratio, power supply on and off time, thickness of refractory lining are some of the crucial factors that are responsible for improving the productivity of Induction Furnace. This paper presents the results of a study where an attempt is made to optimize the specific energy consumption and alternatively productivity. The correlation between various parameters was found in order to optimize the results. To get the optimum results TOPSIS was applied .Finally, the results of the study confirm the common connotation that less specific energy consumption leads to more productivity. Academicians and practitioners could use the results as a guideline for studying effects of various induction furnace parameters

The inspiration for this project comes from the fact that 3D printer is really innovative and revolutionary idea but along with that they are very costly, one cannot afford the 3D printer just for fun or to use at home just to create ideas into reality. One can create an affordable 3D printer by using equipment in their surrounding or probably at home. The technology of 3D printing can be used to create imagination into reality, parts of the machinery of equipment which are not available in the market, prototypes of new ideas and most importantly for fun. Due to higher prices, its access to world is very limited but through this work there will be an increase in the access of 3D printers. Obviously, this isn't going to be fancy but it will show the basics of how the 3D printer works. In the current work the Design and Fabrication of Dual Nozzle Fused Deposition Modelling 3D Printer is developed at low cost.

Wear type rail corrugation is an ongoing problem. Because the current solutions are not cost
effective, further investigation is required to find how to predict the corrugations, leading to
possible prevention methods.

The purpose of this thesis was to create a test rig to simulate these corrugations so that the
results can be studied. Also, existing Matlab and C code used to simulate corrugations on real
wheel-rail systems was modified to predict the results of the test rig. Although it would have
been preferable to run the test rig and compare the results to results from the code, the rig was
not finished in time due to necessary last minute design changes.

The test rig design was completed and it is in the final stages of construction, soon to be ready
for testing. The analytical methods and the code were verified to correctly represent the test rig
dynamics allowing them to be compared to future results from the test rig.

The main aim of any design must not solely be targeted on customer satisfaction however conjointly customer safety following this the amount of accidents are witness solely because of poor lighting facilities provided in automobiles on curved road static headlights are insufficient since they point tangential it along any point of curve instead of pointing in the vehicles direction so to avoid this problem steering controlled headlamp system has been projected which might hopefully flip out to be a boon to the individual driving through the sinusoidal roads throughout night times. Special safety features are built into cars for years some for the security of car’s occupants only, and some for the security of others. One among the alternatives available in design and fabrication of steering controlled headlight system. car safety is important to avoid automobile accidents or to minimise the harmful effect of accidents, especially as concerning human life and health. automobiles are controlled by incorporating steering controlled headlight mechanism. The Ackerman steering mechanism helps the motive force to guide the moving vehicles calls on the road by turning it right or left consistent with his needs thus a combination of the steering system and embedded system link kills the headlights within the direction as per the rotation of the steering wheel. this mechanism has been incorporated in BMW, Audi Q-7 and Benz etc., to make sure a safer drive, but our main aim is to implement the system in all vehicles at lower cost.

In the Indian Academy, Agriculture plays a important role. Over the last few decades, Indian agriculture has recorded good growth. Implementing done in this area. The multipurpose farming robot is a fundamental a new ideas in this field is very important, although a lot of work has been major agricultural machine for full yield. A laborious technique is the conventional method of weeding, sowing seeds and spraying pesticides. In India, bullocks, horses, and buffalo are still used by many farmers for agricultural operations. This would not satisfy the need for agricultural energy needs, in comparison to other countries around the world. We assume that human and animal efforts can be replaced from an economic point of view by some advanced mechanism that will be ideal for small-scale farmers. We are therefore designing this prototype and assume that it will fulfil all requirements and problems in real life. India is a country focused on agriculture in which 70% of individuals rely on the results of farming. But if we observe that with population growth the farm is spread among the family and because of this, farmers in India kept only two acres of farm on average. Economically, farmers are still very poor because they are unable to afford tractors and other expensive machinery, so they use conventional farming methods. So, we are designing this machinery that will fulfil all this need and solve the problem of labor. The paper deals with multi-purpose agriculture machine for seed feeding, spraying pesticides, fungicides, and fertilizers and cutting. Thus paving way for a more economical and multi-usable equipment for farmer which is also easy to clean and maintain, easy to handle and do not require fuel, hence cost gets reduced and helping farmers to a great extent in their fields

With numerous responses established on Taguchi L9, orthogonal array coupled with current work proposes a novel methodology for optimizing machining parameters on turning of AA 6063 T6 aluminum alloy. Experimental assessments are accomplished on AA 6063 T6 aluminum alloy. Turning trails are carried out under dry cutting conditions using an uncoated carbide insert. Cutting parameters such as cutting speed, feed rate, and depth of cut are optimized in this effort while numerous responses such as surface roughness(Ra) and material removal rate are taken into consideration (MRR). From the grey analysis, a grey relational grade(GRG) is calculated. The optimal amounts of parameters have been identified based on the values of grey relational grade, and then ANOVA is used to determine the significant influence of parameters. To authenticate the test result, a confirmation test is executed. The result of the experiments shows that by using this method. the turning process responses can be sig...
