摘要
分析了工程车辆传动系统自激振动产生的原因和机理 ,并建立了数学模型 .经分析 ,工程车辆传动系统在高滑转率下常会失稳而产生自激振动 ,对车辆产生不利影响 .
In this paper,the mathematic model of vehicle powertrain was established and solved by average method to get the formula of the self-excited vibration amplitude.The limit cycles of the self-excited vibration were given.In addition,the factors influencing the amplitued,such as the adhesion coefficent and slip,the thrust torque,speed and damping,were discussed.
