There are many concepts to build high speed or high precision manipulators, but only a few of them can serve to obtain high speed together with high precision. Mathematical modeling of simple XY manipulator is carried out XY manipulator uses typical Double Flexural configurations. Static and dynamic analysis is carried out using MATLAB. Static analysis is carried out to determine static deflection of motion stage with force. It is observed that force deflection curve is linear. Dynamic analysis is carried out to determine frequencies and mode shapes of flexural manipulator. Further, Finite Element software ANSYS is used to carry out static and dynamic analysis of basic DFM configuration and few XY mechanisms. It is observed that close matching of FEM results with model developed.

All countries use different wind load standards. These different wind load standards are compared with each other in some studies. This paper describes a parametric study of wind load calculations on Vertical Pressure Vessel as per Indian Standard IS-875 (Part 4) (Ammendum 3rd 2006) with their latest addendums. The wind loads calculated, are applied to the design of structures to prevent failure due to wind. Calculated wind pressures as per different code on a Pressure Vessel produce actual loads on the structure. A good structural system for wind design is typically a strong, heavy system with robust connections to help resist loads as the wind blows across and over the structure. The Vertical Pressure Vessel is assumed to be made up of 3 components; First bottom dish which is supported on skirt, second intermediate Shell and Third top dish .The Vertical Pressure Vessel is 6.25 m tall and assumed which is located in urban terrain. The design wind speeds acting on vessel are to be calculated from corresponding codes. The wind force are calculated on each component as per Code procedure and checked for variation occurred. The factors like Basic Wind Speed, Terrain Category, Exposure Category, Damping factor are changed during calculation, the variation on wind force is plotted on graph.

The leveller machine is used to flatten out and level the coiled sheets for finding applications in various industries. Roller leveling is essentially a bending process. The out of flat part, sheet or plate is deformed by a series of alternating bends created by passing the sheet, or plate between upper and lower sets of leveling rollers. The power is transmitted to the rollers from the motor via a gearbox and the outputs of the gearbox are connected to the rollers through spindle shafts with the help of universal joints. The large angle of these universal joints affects its efficiency and thereby decreases its life. Hence this angle is to be reduced and one way of achieving this is by compacting the gearbox. The size is drastically reduced by constructing the layout of the gears in such a way, that the space between the outer surface of the gear and the shaft is utilized by arranging the gears in several lateral and longitudinal planes. The main aim of the paper is to describe this innovative layout and its design verification.
