采用作者建立的非线性时变轮胎模型,仿真分析了路面不平度幅值及路空间频率变化对地面附着性能的影响.得出路面不平度增大时,使路面对车轮的附着能力下降,因而使制动距离增长的结论.同时说明非线性时变轮胎模型能较真实地体现路面不平度的影响,对不平路面上车辆制动性能仿真是一个有效的轮胎力学模型.

Using a nonlinear time varying tyre model, this paper simulatively analyzes the influence of road surface roughness amplitude and road spatial frequency on automobile-ground adhesion ability. The result shows that with the increase of road surface roughness, the tyre adhesion ability declines, and the automotive braking distance increases. Moreover, the reliability of the nonlinear time varying tyre model in reflecting the influence of the road surface roughness is validated. It is testified that this model is an effective dynamic one in the simulation of automotive braking performance on uneven road.
