基于有限元法进行铁道车辆橡胶元件的设计

The design of rubber parts in railway vehicles with finite-element analysis

介绍了描述橡胶类超弹性材料的几个应变能函数 ,并从橡胶材料实验数据的曲线拟合得到Yeoh模型的材料常数 ,进而采用有限元法对铁道车辆用橡胶元件粘合圆柱块及圆锥形橡胶弹簧进行了设计分析。

Several strain energy functions that describe hyper elastic rubber are introduced.The material constant of Yeoh model are derived from the test data of rubber material.The bonded rubber cylinders and conical rubber spring in railway vehicles are analyzed by FEA.
