应用多体动力学理论，建立了动力总成悬置系统的力学模型。以动力总成悬置系统六自由度能量解耦为优化目标，以刚度比和固有频率合理配置为约束条件，以悬置刚度、位置和角度为设计变量，构造了动力总成悬置系统的优化模型。在Windows平台上利用Matlab开发了动力总成悬置系统设计软件。该软件主要实现了汽车动力总成悬置系统的性能分析、力学分析、优化设计和生成设计分析报告。采用该软件对某载重汽车的动力总成悬置系统进行优化设计及性能分析。优化结果表明，解耦率明显提高，固有频率分布更合理。

Applying the multi-dynamic theory,a dynamic model of the powertrain mounting system of motor vehicles is established. An optimization model for the powertrain mounting system is constructed,in which decoupling efficiency of six freedom vibrations is selected as object function,and stiffness radio and inherent frequency distribution as constraint conditions,the stiffness,installation positions and angles of the mounts as design variables of optimization. The software of design and analysis in powertrain mounting system is developed by Matlab in Windows platform. The software mainly realizes performance analysis,mechanical analysis,optimal design and generating a-nalysis report of powertrain mounting system. Based on the software,as an example,powertrain mounting system of a truck is designed and analyzed. The optimization results show that the decoupling rate is obviously improved and the inherent frequency distribution more reasonable.
