摘　　要：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面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 。Influences of the changes of the amplitude and space frequency of road surface roughness on adhesion ability are simulated and analyzed by means of the nonlinear and time varying tyer model made by the author. The conclusions, which adhesion ability of road to the tyre reduces so that braking distance increases while road surface roughness increases, are obtained. Meanwhile, it is seen that the nonlinear and time varying tyre model is useful for the simulation and analysis of braking performances of vehicles on rough road surface because it reflects the real influence of the road surface roughness on tyre.
