摘　　要：汽车动力总成液阻悬置经常受到发动机与路面双向的频变和幅变的的作用。橡胶主簧对液阻悬置在复杂工况下的性能有着重要的影响,为了研究橡胶主簧的减振性能,利用有限元方法与试验相结合的方法,根据工作条件选取相应的本构模型,与试验数据对比来获得减振橡胶材料在动态条件下的性能,得到了理论与试验基本一致的应力应变数据。该研究方法为工业中各种减振隔振橡胶材料有限元分析提供了基础理论,为汽车动力总成悬置设计提供一种有效的研究方法。The automobile powertrain hydraulic mount is often affected from the engine and the road because of inputing the different frequency and amplitude of engine and road.It is very important to study rubber spring performance which it influenced the work of hydraulic mount.It is combined with the method of using the finite element method and test according to the working conditions to study the damping performance of rubber spring.The appropriate constitutive model is selected.And the data is comparied between finite element mothod and test in fact.The theory and experiment data is almost the same.The research provides a theoretical basis for automobile power mount.It is an effective research method for the industry vibration and isolation rubber material.
