摘　　要：本文对被动式液阻型橡胶悬置及动力总成-液阻悬置系统的设计分析方法和研究成果进行了较系统的述评和总结。首先介绍了汽车动力总成液阻悬置的应用概况,总结、阐述了汽车动力总成悬置系统所要求的理想隔振特性。然后综述了节流孔型、惯性通道型、惯性通道-固定解耦膜型、惯性通道一活动解耦膜型等典型被动式液阻悬置元件的结构原理、集中参数模型、动态特性及其参数设计分析结果,同时综述了动力总成-液阻悬置系统隔振生能研究概况及设计分析方法,其中着重介绍了德国Freudenberg公司、美国Ohio州立夫学、日本Nissan公司等主要研究者的研究工作及结果。In this paper, the design and analysis methods for the passive hydraulically damped mount and the powertrain mounting system are reviewed. First of all, the applications of the hydraulically damped mounts are briefly introduced. Then the desired vibration isolation characteristics for the automotive powertrain mounting systems are summarized. Tirdly, the construction principles, discrete parametric models and dynamic characteristics of typical hydraulically damped mounts including simple orifice, inertia track, inertia track-fixed uncoupler, and inertia track-free uncoupler are summarized. Furthermore, the researches on vibration isolation performances and analysis methods of powertrain systems with hydraulically damped mounts are reviewed. The emphases of the survey are on the researches of Freudenberg Corporation in Germany, the Ohio State University in U. S. A., Nissan Inc. in Japan, etc.. Finally, some comments about the future investigations in this field are given as concluding remarks.
