摘　　要：以某轻型客车为研究对象,建立了包括动力总成和车身两个刚体的12自由度动力总成悬置系统的ADAMS动力学模型,提出了一种试验与理论计算相结合确定发动机怠速激励的方法。采用该模型对动力总成悬置系统怠速隔振性能进行了仿真计算与分析。仿真结果与试验结果对比表明二者吻合较好,说明所建立的12自由度ADAMS模型和确定的发动机激励是准确的。This paper takes a light duty bus as study object to establish ADAMS dynamic model which includes twelve degrees of freedom powertrain mounting system of two rigid bodies of powertrain and body,and presents a method to determine engine idle excitation which combines test and theoretical calculation.The paper uses this model to carry out simulation calculation and analysis of idle vibration isolation performance of powertrain mounting system.The comparison between simulation results and test results shows that these two results agree well,indicating that the established twelve degrees of freedom ADAMS model and the engine excitation are correct.
