摘　　要：发动机液压悬置是非线性很强的隔振元件,其动特性因激振频率和激振振幅的改变而改变。试验分析和理论研究是研究液压悬置的两种基本方法。文中通过分析典型液压悬置的结构特征,全面总结液压悬置的试验方法、理论模型和优化设计方法等方面的研究现状,分析了将试验研究和理论分析相结合、采用系统参数识别方法对液压悬置进行研究的可行性,并探讨了最优试验设计准则。Hydraulic engine mounting is a strong nonlinear vibration isolating component,and its dynamic characteristics varies with the exciting frequency and amplitude.Experimental analysis and theoretical study are the two basic methods for hydraulic engine mounting study.In the paper,by analyzing structure features of typical hydraulic engine mountings,the current status of studies on test methods,theoretical model and optimization design methods of hydraulic engine mountings are summarized,and the feasibility is brought forward to combine experimental research with theoretical analysis and to apply the system parameter identification method to study on hydraulic engine mountings,and the optimal test design criterion is discussed.
