摘　　要：利用Trucksim重型汽车动力学仿真软件,对某款重型半挂式汽车在低附着路面左右车轮附着系数不一致情况下进行紧急制动的行驶工况进行了仿真研究。研究结果表明在低附着路面进行紧急制动时,有ABS控制的紧急制动,其簧载质量产生的侧倾角、横摆角、横摆角速度要远小于无ABS控制的,左右车轮制动力矩一致性较好,可有效避免因紧急制动而产生的侧滑、甩尾、折叠现象。ABS控制可显著改善重型半挂式汽车在低附着路面紧急制动时的行驶稳定性和安全性。In this paper,the Trucksim softwareis is used to simulate the driving conditions of a heavy semi-trailer vehicle during emergency braking when the right and left wheels do not have the same adhesion coefficients on a low adhesion road.The research results show that when emergency braking is carried out on low-adhesion road,the roll angle,yaw angle and yaw angular velocity generated by sprung mass are far smaller than those generated without ABS control,and the right and left wheel braking torque is consistent,which can effectively avoid sideslip,tail swing and folding phenomena caused by emergency braking.ABS control can significantly improve the driving stability and safety of heavy semi-trailer vehicles during emergency braking on low adhesion road.
