Contact Stress Analysis of Packer Rubber Based on ANSYS Software

摘要

In this paper three-rubber compression packers are regard as study objects, hyper-elastic constitution equation Yeoh has been used, the ANSYS mechanical model of packer rubber has been established by ANSYS software, the influence of axial setting force and frictional coefficient on the contact stress of packer rubber has been analyzed. The research results indicate that with the increasing of setting force, the axial compression amount and Von Mises stress increase; with the increasing of frictional coefficient between rubber and casing, the Von Mises stress of the intermediate rubber decreases slowly.
