摘要: 环形橡胶减震器作为车辆传动装置的支撑部件,其径向刚度直接影响车辆传动装置的运行品质与机械寿命,其减震效果与橡胶材料的理化特性、减震器的结构形式密切相关。基于Mooney-Rivlin模型,在ANSYS-Workbench平台上进行环形橡胶减震器径向受载工况的仿真分析,对比采用两种橡胶材料的环形减震器在不同温度环境条件下的径向刚度,并以环形橡胶减震器最大径向刚度为优化目标,在橡胶层应力强度约束条件下进行环形减震器的几何参数优化。结果表明,参数优化后提高了车辆传动系统可靠性,所得结果为橡胶减震器的力学性能研究提供了方法和依据。

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.
