摘　　要：本文以Audi 100轿车动力总成液压悬置为例,建立了惯性通道-解耦膜式液压悬置的非线性力学模型和数学模型,对其原点动特性和跨点动特性进行了仿真计算,经与试验结果相比较,二者吻合良好。文中深入分析了各参数对动特性的影响规律,初步提出了惯性通道-解耦膜式液压悬置的参数选择原则。A non-linear analytical model of the hydraulic engine mount with inertia track and uncoupling membrane used in car Audi-100 is set up. The original-point and cross-point dynamic characteristics of the hydraulic mount are calculated, and the numerically simulational results agree well with the experimental ones. The influence of parameters on the dynamic characteristies of the mount is analysed and the choice of mount design parameters for optimal vibration isolation performance is discussed.
