首先建立了惯性通道－解耦膜式液压悬置隔振系统的非线性力学模型和数学模型，然后以Audi100轿车动力总成液压悬置为例，对其正向隔振性能进行了仿真计算和实验研究，理论计算结果与实验结果在0～300Hz频段上吻合良好。深入分析了液压悬置的各参数对其低、高频隔振性能的影响规律，较详细地阐述了惯性通道－解耦膜式液压悬置的参数选择及匹配方法，从而为设计此类液压悬置提供了更充分的理论依据。
First of all, the nonlinear mechanical model and mathematical model of inertial passage-decoupling membrane hydraulic suspension vibration isolation system are established. Then taking the hydraulic suspension of Audi100 sedan as an example, the forward vibration isolation performance is simulated and analyzed. Experimental study, the theoretical calculation results and experimental results in the 0 ~ 300Hz band good agreement. In-depth analysis of the various parameters of the hydraulic mount its low frequency and high frequency vibration isolation performance of a more detailed elaboration of the inertial channel - decoupling membrane hydraulic mount parameter selection and matching methods, so as to design such hydraulic Suspension provides a more adequate theoretical basis.
