不平路面上制动附着系数变化的仿真分析

Simulation and Analysis of Variation of Adhesive Factor on Rough Road Surface

摘要: 文章采用一种非线性时变轮胎模型，仿真分析了当路面不平度幅值和频率改变时，附着系数的变化规律，并从理论上解释了车速提高时制动附着系数下降的原因，为进一步分析附着系数的影响因素提供依据。

Abstract: A nonlinear tyre model is proposed in this paper．The variation laws of the adhesive factor while the amplitude and frequency of the road surface changes are simulated and analyzed by means of the tyre model. The conclusion that adhesive factor decreases while the vehicle velocity incereasing is explained. 
