摘要
建立了拖拉机-挂车机组在不平路面上制动过程的动力学模型,提出了符合车辆在不平路面上制动特征的自适应轮胎力学模型。仿真分析了随机路面上的制动过程,得出当路面不平度增大时,拖拉机-挂车机组的制动距离增长、制动加速度减小等有价值的结论
In this paper a tractor trailer combination model braked on rough road surface is established. Adaptive footprint tyre model braked crossing rough road surface is presented. Exemplary results, which the more braking distance of tractor trailer combination increase, the more braking deceleration decrease if the more the road surface is rough, are obtained from simulation and analysis of tractor trailer combination braking process on even and uneven road surfaces.
