摘要
液压衬套作为汽车悬架系统的重要隔振元件,其静、动特性分析和隔振性能匹配在其研究开发中具有重要意义。利用液固耦合有限元方法对液压衬套进行建模分析,通过静态和动态仿真与试验的对比验证了模型的正确性。仿真计算衬套关键参数,为后期的试验和参数化分析提供指导,并利用该方法对参数化分析结果进行了结构验证。
As the important vibration isolator used in suspension system,analyses of static and dy-namic characteristics and matching of vibration isolate performance for hydrobushing are important in research and development.Based on fluid-structure interaction finite element method,FSI finite ele-ment model of hydrobushing is built.The static and dynamic simulation of the FSI model are conduc-ted to validate the model.Based on the verified model,key parameters of hydrobushing are simula-ted.The parameters will provide guidance for the test and parametric analysis.Meantime,the method is used to verify the results of parametric analysis.
