摘要
液压悬置在发动机隔振方面起着重要的作用,具有复杂的动特性。文章以惯性通道式液压悬置为研究对象,建立了橡胶主簧与上液室的有限元模型,并进行了系统参数识别,计算出橡胶主簧的静态特性及上液室的体积特性;同时还建立了惯性通道式的液压悬置有限元模型,应用基于任意拉格朗日法(ALE)的流固耦合理论,进行悬置静态特性和动态特性的仿真。仿真结果表明,应用ALE有限元法分析液压悬置是可行的,所得结果为悬置的生产设计提供了参考。
Hydraulic engine mount（HEM）,which has complicated dynamic characteristics,plays an important role in reducing the vibration of engine.A HEM with inertia track is chosen as the research object,and the finite element model of rubber spring and upper fluid chamber is established in this paper.The system parameters are calculated,such as static characteristic of rubber spring and the compliance of upper chamber.The finite element model of the HEM with inertia track is also established and the static characteristic and dynamic characteristic of the mount are simulated by applying the fluid-structure interaction theory based on the arbitrary Lagrangian-Eulerian（ALE） formulation.The simulation results show that the ALE finite element method is feasible,and the results provide a reference for production and design of mounts.
