Abstract Based on the distribution and layer characteristics of prestressed steel wire-wound cylinder four-column hydraulic press, its supporting parts not only bear constant stress caused by internal pressure, but also withstand alternating cylinder, then produce gradual accumulation plastic deformation. This paper uses theoretical calculation formulas to solve corresponding parameters, establ...

Abstract The Piston is a crucial element of an I.C engine. reciprocating component the engine that converts thermal energy and pressure liberated by ignition air-fuel into mechanical work. design selection material challenging assignment for designer. This paper describes procedure piston four-stroke petrol optimization with different materials was carried out in present analysis done consideri...

The work presents the Finite element study of the effect of elliptical chords on the static and dynamic strength of tubular T-joints using ANSYS. Two different geometry configurations of the T-joints have been used, namely Type-1 and Type-2. An elastic analysis has been considered. The Static loading conditions used are: axial load, compressive load, In-plane bending (IPB) and Out-plane bending...

MEMS (Microelectromechanical Systems) refers to the technology integrating electrical and mechanical components with feature size of 1~1000 microns. MEMS comb accelerometers have been successfully applied for air-bag deployment systems in automobiles. In this paper, the design optimization of a polysilicon surface-micromachined MEMS comb accelerometer is discussed. The device uses folded-beam s...
