Analytical method and software technology of finite element plays a very important role in structural analysis.By using HyperMesh software as a pre-processing

the finite element model on basis of hexahedral is established.Focus on elastomer modeling

the actual working condition of coupling system is simulated.By using RADIOSS solver

the finite element calculation of stress and strain for screw and rubber elastomer is carried out.The strength

stiffness and other indicators of the parts are evaluated.
