摘　　要：该文建立了软路面——车辆系统的扭转振动、垂直振动和纵向振动耦合的动力学模型，并把路面不平度、发动机角速度和牵引负荷作为三个激励引入到传动系扭振的多分支系统中。推导出车辆振动的频响函数、振动响应的功率谱密度和振动响应均方根值的计算公式。In this paper,the dynamical model which was coupled of vertical vibration,horizontal vibration and torsional vibration was established. The vehicles transmission system was considered as a multi branch system.The spectrum of terrain roughness, engine angular velocity and drawbar pull were three excitation sources of the system. With a self compiled program, the root mean square and power spectrum of the responses can be simulated and calculated.Through experiments, its verified that the dynamical model is correct.
