摘 要: 介绍了橡胶作为超弹性材料在改善机车车辆动力学方面的重要作用、橡胶的基本力学性能、应变能函数和有限元法常用的几种本构模型及其不同的应用范围;再列举了几种典型机车车辆用橡胶零件的有限元分析和产品试验结果对比情况,包括应力、应变、产品的疲劳性能、刚度性能等。通过对橡胶弹性元件的有限元分析计算经验的积累,同时与试验结果结合起来对分析结果进行适当修正,完全可以达到降低开发成本、提高效率的目的。 The importance, general mechanical property, strain energy functions of rubber as super-elastic material are introduced, as well as several kinds of constitutive models used in FEM and their different applications. The FEA and test results of typical rubber components in the railway vehicle are listed, including the stress, strain, fatigue performance and stiffness etc. With the experiences in the FEA calculations of rubber elements, and with certain correction on the analysis results in combination with the test results, the purpose to lower down development cost and improve efficiency could be achieved.
