摘　　要：通过对动力总成悬置系统的动特性进行理论分析,建立了典型工况下四点支撑式动力总成上关键点的数学振动模型。利用MATLAB/SIMULINK仿真技术模拟了动力总成上关键点在启动、制动、转向和稳态四种典型工况下的振动位移特性,为动力总成悬置系统和相关零部件的空间布置设计提供了参考。稳态工况下动力总成上边缘关键点的振动位移幅度在试验和仿真上基本一致,表明了仿真模型的可靠性。Based on theoretical analysis of the powertrain mounting system dynamic characteristic, the mathemati- cal vibration model of powertrain mounting system with four shores under typical working conditions was set up. Using MATLAB/SIMULINK simulation technology simulates the vibration displacement characteristics of the powertrain＇s key point in starting, braking, steering and steady-state the four kinds of typical working conditions, which provides a reference for the spatial arrangement and design of the powertrain mounting system and related parts. Under steady-state conditions, the vibration amplitude of the upper edge＇s key point of the powertrain in both experiment and simulation is generally same, so it shows that the simulation model is reliability.
