摘　　要：考虑包含了液阻悬置的悬置系统与传统橡胶悬置系统的不同,建立了某型汽车动力总成13自由度分析模型。考虑液阻悬置动态特性随频率变化的特点,应用五参数模型描述液阻悬置的动刚度和滞后角。以某型汽车过减速带时动力总成垂向最大位移为设计目标,以液阻悬置五参数为设计变量,优化后的动力总成垂向最大位移满足设计要求。Considering the dif ferences between hydraulic powertrain mounting system and rubber mounting system,a type of vehicle 13-Degrees of Freedom(DOF) analyzing model is established.Considering the characteristics of the dynamic characteristics of the hydraulic engine mounts with frequency,a fiveparameter model is used to describe the dynamic stif fness and loss angle of the hydraulic engine mounts.The maximum displacement of the powertrain in the vertical direction of a certain type of vehicle is the design goal.The five parameters of the hydraulic engine mounts are used as design variables,and the maximum displacement of the optimized powertrain meets the design requirements.
