The Radial Stiffness Calculation and Parameter Optimization of the Annular Rubber Shock Absorber Based on Mooney-RivlinModel

doi:10.12382/bgxb.2022.A008

Abstract

Abstract: The annular rubber shock absorber is a supporting component for the vehicle.High performance and long mechanical life of transmission equipment rely on the radial stiffness of shock absorber.The damping effect is related to the physicochemical property of rubber and the mechanical structure of shock absorber.Based on the Mooney-Rivlin model，the operating process of shock absorber under the radial load is simulated on ANSYS-Workbench，and the radial stiffnesses of shock absorbers with two different kinds of rubbers under several temperature conditions are compared.The geometric parameters of shock absorber under the Stress intensity of rubber are optimized to get the largest radial stiffness.These works not only improve the reliability of the transmission equipment，but also provide a method and reference for studying the rubber shock absorbers.

Key words: vehicle, annularrubbershockabsorber, radialstiffness, Mooney-Rivlinmodel, finiteelementmethod, ANSYS-Workbench
