摘要
建立了汽车在不平路面上制动过程的动力学模型，提出了反映路谱对车轮制动影响的非线性时变轮胎力学模型，仿真计算了ＢＪ－２１２汽车在随机路面上的制动过程，通过分析说明路面不平度对车辆制动性能存在显著的影响，得出了路面不平度增大时，汽车的制动距离增长，制动加速度减小等有价值的结论。
A mathematics model of automobiles braked on a rough road surface is established. The nonlinear and time varying footprint tyre model braked crossing the rough road surfaces is presented. Braking processes of BJ 212 automobile crossing even and uneven road surfaces are simulated. Exemplary results show that the more braking distance of automobile increase, the more braking deceleration decrease if the more rough the road surface is.
