Analysis of the Amplitude of the SelfExcited Vibration in Vehicle Power Train and Factors Influencing the Amplitude

In this paper, the mathematic model of vehicle power train 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 amplitude，such as the adhesion coefficient and slip， the thrust torque， speed and damping， were discussed.
