Selective laser melting (SLM) is an additive technology that allows for the production of precisely designed complex structures for energy absorbing applications from a wide range of metallic materials. Geometrical imperfections of the SLM fabricated lattice structures, which form one of the many thin struts, can lead to a great difference in prediction of their behavior. This article deals with the prediction of lattice structure mechanical properties under dynamic loading using finite element method (FEA) with inclusion of geometrical imperfections of the SLM process. Such properties are necessary to know especially for the application of SLM fabricated lattice structures in automotive or aerospace industries. Four types of specimens from AlSi10Mg alloy powder material were manufactured using SLM for quasi-static mechanical testing and determination of lattice structure mechanical properties for the FEA material model, for optical measurement of geometrical accuracy, and for low-v...

This paper investigates the dynamic characteristics of pulley systems with different numbers of bolt holes. Models with four, six and eight bolt holes were chosen for the pulley. Three sets of cyclic pressure were applied to the pulley system to resemble the different running revolutions of an engine. The study investigates the effect of the number of holes on the system’s stiffness and natural frequency. Finite element models were used to simulate the obtained deformations, stresses and frequency response function (FRF) for pulley models comprising four, six and eight bolt holes under different cyclic pressures. The results show that the stiffness and natural frequency increased with increasing the number of the bolt holes. This in turn, reduced the resulted deformations and stresses.

with 5% SiC and 10% flyash will have better results and
higher material property when compared with previous
similar researchers. So this composites and process were
recommended for manufacturing of connecting rod for
automobile applications.

Floor beam is a structural part of a fuselage which is used as floor space to passengers, cargo and fixed with fuselage skin. Here, the cross beam has taken as I-section and connected with attach bracket methods of joining. The design of aircraft floor beam is conceptual design for the cost and weight reduction, strength improvement and ease of fabrication of fuselage. Increased weight and less stiffness of the existing floor beam made of aluminum is major problem of present floor beam. Hence, CFRP (carbon fiber reinforced plastics) has chosen for the designing of floor beam in the aircraft. After the selection of material and cross section of floor beam, the whole parameters of cross section of floor has studied and designed in UG NX8 software then the model is imported to Ansys 14.5 for the dynamic analysis and life estimation.

Inert gas shrouding in a tundish can result in the formation of a tundish open eye due to the presence of reversed flows on the upper surface of the tundish. Prolonged presence of open eyes promotes reoxidation of liquid steel and creates harmful inclusions, which can ultimately result in clogging of SENs. In the present study, the impact of open eye size and duration on harmful inclusion formation in the tundish of ArcelorMittal Dofasco’s No. 1CC has been analyzed using a comprehensive quantitative approach encompassing mathematical modeling, thermodynamic calculations, and observations at No. 1CC tundish. Validation work carried out using ASPEX inclusion analysis shows that the major inclusions formed include Al2O3 and Ti-Aluminates.

A piston is a component of reciprocating engines. Its purpose is to transfer force form expanding gas in the cylinder to the crank shaft via piston rod and a connecting rod. It is one of the most complex components of an automobile. In some engines the piston also acts as a valve by covering and uncovering ports in the cylinder wall. In present, work a three dimensional solid model of piston including piston pin is designed with the help of CATIA and SOLIDWORKS software. The thermal stresses, mechanical stresses and couples thermo-mechanical stresses distribution and deformations are calculated. After that fatigue analysis was performed to investigate factor of safety and life of the piston assembly using ANSYS workbench software. Aluminium-silicon composite is used as piston material. The stress analysis results also help to improve component design at the early stage and also help in reducing time required to manufacture the piston component and its cost.

The undesired stick-slip vibration is the main source of PDC bit failures, such as tooth fracture and tooth loss. Therefore, the study of PDC bit failure base on stick-slip vibration analysis is crucial to prolong the service life of PDC bit and improve R.O.P (Rate of Penetration). For this purpose, a piecewise-smooth torsional model with 4-DOF (degree of freedom) of drilling string system improper PDC bit is proposed to simulate non-impact drilling. In this model, both the friction and cutting behaviors of PDC bit are innovatively introduced. The results reveal that the PDC bit is easier to fail than other drilling tools due to the severer stick/slip vibration. Moreover, reducing W.O.B (Weight on Bit) and improving driving torque can effectively mitigate the stick-slip vibration of PDC bit. Therefore, PDC bit failure can be alleviated by optimizing drilling parameters. Besides, a new 4-DOF torsional model is established to simulate torsional impact drilling and the effect of torsional impact on PDC bit's stick-slip vibration is analyzed by applying an engineering example. It can be concluded that torsional impact can mitigate stick-slip vibration, prolong the service of PDC bit and improve drilling efficiency, which is consistent with the field experiment results.

Hooks are employed in heavy industries to carry tonnes of loads safely. These hooks have a big role to play as far as the safety of the hoist loaded is concerned. With more and more industrialization the rate at which these hooks are forged are increasing. This work has been carried out on one of the major hoist hook carrying a larger load comparatively. So in present work the solid modeling and finite element analysis of crane hook has been done using Solidworks and ANSYS workbench. For analysis purpose virtual model of crane hook is prepared by picking data from design data book. Curved beam flexure formula is used for determination of stresses in crane hook analytically. Finite Element Analysis have been performed on trapezoidal cross sections. To investigate the static stress results, both finite element method and exact solution method are applied and compare the stress results obtained by finite element and exact solution methods. From the output of these analyses it is observed that results obtained are in close agreement with each other and maximum stress concentration occurs at inner most surfaces.

Centre and the Cranfield Impact Centre (CIC) inside Cranfield University. Carbon Fibre Reinforced Plastic (CFRP) tube is an important material for the lightweight design of automotive and aerospace structures. Simulation methods of Aluminium and CFRP thinwalled tubes subjected to axial compression and filled with Aluminium foam was investigated in this thesis project. For the Aluminium tube and Aluminium foam, *MAT_3 and *MAT_63 were employed respectively to execute the simulations of the empty and filled tube. To obtain the ideal element size for the mesh, a theoretical method was used to correlate the results with the numerical values obtained in LS-DYNA software. For the CFRP tube, the Finite Element (FE) model was built based on the twolayer shell model, using the *MAT_54/55 material formulation, failure strategy and the parameters sensitivity of the model. Then the simulation model was verified by using duplicate specimens comprised of carbon fibre/epoxy unidirectional prepreg tape. Furthermore, the modelling method of crush trigger B45 and different types of loading speed (static and dynamic) were analysed. A correlation was made between the physical testing results and the numerical values obtained from LS-DYNA to define the ideal values for the strength parameters.

A pressure vessel is defined as a container with a pressure differential between inner and outer surface. The inside pressure is usually higher than the outside, except for some isolated situations. Pressure vessels often have a combination of high pressures together with high temperatures both internally and externally. Any leak under operating pressures may lead to failure of the vessel which causes extensive physical injury and property damage. Because of such hazards it is imperative that the design be such that no leakage can occur. In addition these vessels have to be designed carefully to cope with the operating temperature and pressure. This project set out to design and analyzes a custom made pressure vessel for the required application. Explore applicable methods using finite element analysis in pressure vessel analysis. Having tested three ax symmetric models, the preliminary conclusion is that finite element analysis is an extremely powerful tool when employed correctly. Problems such as local stress risers, unrealistic displacements and understanding how to use such data become extremely important in this kind of analysis. The difficulty in analysis of stress and strain in structural engineering depends on the structure involved. As the structure grows in complexity, so does the analysis. However, these Calculations often provide solutions only for the maximum stress and strain at certain points in the structure. This highlights the key to proper use of finite element analysis. Process starts with performing basic calculations of pressure vessel by using ASME Pressure Vessel code and BIS Unfired pressure vessel code. Once we obtain results from basic calculation we develop software for iteration of vessel parameters. This gives a fine refinement and accurate parameters that require to design a pressure vessel. Later these parameters are developed to 3D modeling in Solid Works 2013, followed by analysis of stress and deflection by ANSYS WORKBENCH 13.0. The dissertation deals with design and analysis of Pressure Vessel with Integral Type Flange. Keywords: ASME Pressure Vessel Code, Modeling of Pressure Vessel.

The Engine cylinder is one of the major automobile component, which is subjected to high temperature variations and thermal stresses. In order to cool the cylinder, fins are provided on the surface of the cylinder to increase the rate of Heat transfer. By doing thermal analysis on the engine cylinder and fins around it, It is helpful to know the heat dissipation rate and Temperature Distribution inside the cylinder. We know that, By increasing the surface area we can increase the heat dissipation rate, so designing such a large complex engine is very difficult. The main aim of the present project is to analyse the thermal properties like Directional Heat Flux, Total Heat Flux and Temperature Distribution by varying Geometry(Circular, Rectangular),material(Aluminium Alloy, Magnesium Alloy) and thickness of Fin (3mm,2mm) of an approximately square cylinder model prepared in SOLIDWORKS-2013 which is imported into ANSYS WORKBENCH-2016 for Transient Thermal analysis with an Average Internal Temperature and Stagnant Air-Simplified case as Cooling medium on Outer surface with reasonable Film Transfer Coefficient as Boundary Conditions.

This presentation introduces the design optimization of ANSYS Workbench analysis using VisualDOC. VisualDOC is a powerful tool for multidisciplinary design process integration, execution and automation. It offers a friendly interface that allows the users to easily define the components and create the work flow for design optimization. ANSYS Workbench is an innovative project platform that guides the users through complex multiphysics analyses via ‘drag-and-drop’ tactic. The project-level parameter management and update mechanism enables external execution of ANSYS without interfering the sub-system level analyses. This presentation demonstrates the implementation of multidisciplinary design optimization for ANSYS analysis using VisualDOC as optimizer. The coupling between VisualDOC and ANSYS is accomplished in an automated manner such that no programming effort is required. A design optimization of a mixing elbow, a multi-objective optimization of an aero-elastic wing, and a response-surface-based optimization for a flapping plate are used to illustrate the proposed functionality.
