摘要
以橡胶悬置为研究对象,基于经验参数和曲线,根据实测邵氏硬度确定Mooney-Rivlin模型参数。根据极端载荷划分7种工况,运用HyperWorks有限元分析软件进行仿真分析。结果为橡胶最大应变出现在主簧根部切线方向,与实际失效位置一致。对比7种工况的最大应变后发现,只施加Mx情况下可代替全扭矩载荷情况,为简化载荷奠定基础。
Taking rubber mount as the research object,the Mooney-Rivlin model parameters were determined according to the measured Shore hardness based on the empirical parameters and curves.Seven working conditions were divided according to the extreme load,and the HyperMesh finite element analysis software was used for simulation analysis.The results show that the maximum strain of rubber appears in the tangent direction of the root of the main spring,which is consistent with the actual failure position.By comparing the maximum strain under seven working conditions,the full torque load condition can be replaced under the condition of only applying Mx,which lays a foundation for simplifying the load.
