轮式车辆动力传动系自激振动研究（Ⅱ）——自激振动系统的能量反馈与控制系统分析

提出了轮式车辆传动系的自激振动中地面附着力输给系统的振动能量和系统消耗的振动能量的计算公式，研究了该自激振动的反馈控制系统，得知在开始产生自激振动时，瞬时滑转率在地面附着力与滑转率关系曲线的负阻尼区中变化，但当自激振动的振幅增大到超过某一值后，瞬时滑转率的变化范围扩展到正阻尼区，从而控制了自激振动的振幅

Research on the Self Excited Vibration in Wheeled Vehicle Powertrain(Part II) Analysis of Energy Feedback and Control System

In this paper,formulae of energy input to the self excited vibration system and the energy consumed in wheeled vehicle powertrain system were presented. In addition, the feedback and control system of the self excited vibration were studied. The results indicate that the slip vibrates in the negative damping area of the adhesion force at first,but when the vibration amplitude exceeds a certain value,the slip extends to the positive damping area, hence the amplitude is hindered from increasing infinitely.
