Research on the Self excited Vibration in Wheeled Vehicle Powertrain( Part I)——Mechanism Analysis of the Self excited Vibration

In this paper, the mechanism of the self excited vibration in wheeled vehicle powertrain was studied.For this purpose, the mathematics model was established, and the analysis of the phase plane was presented.The results indicated that the main cause of the self excited vibration is that the adhesion force became smaller as the slip rate increased.
