摘要/Abstract

摘要： 使用多体动力学软件Trucksim构建双挂汽车列车模型,并根据仿真结果进行瞬态侧翻状态研究。通过仿真不同车速下的瞬态阶跃响应,获得汽车列车的各个轮胎垂直载荷、侧向加速度、横摆角速度、车辆侧倾角以及铰接角等状态变量的变化规律。根据轮胎垂直载荷瞬态变动判断车辆各轴发生临界侧翻的先后顺序,并与侧向加速度阈值评价结果对比,发现第一节半挂车车轴最先发生临界侧翻危险。通过变化车速与转向盘转角,得到临界侧翻的稳定行驶速度域。

Abstract: A vehicle model was constructed using the multi-body dynamic software Trucksim to investigate the transient rollover state according to the simulation results. Through the transient step response simulation under different speeds, the change laws of the state variables were acquired, including the vertical load on the tire, lateral acceleration, yaw rate, roll angle and articulation angle. According to the transient changes of the vertical load on the tire, the sequence of critical rollover of the axles was determined, which was compared with the lateral acceleration threshold evaluation results. It is shown that the first semitrailer axle is the earliest prone to critical rollover risk. By changing the vehicle speed and the steering wheel angle, a vehicle speed stability region of the critical rollover is acquired.

Key words: vehicle engineering, tractor and double trailer combination, lateral stability, transient rollover state, tire vertical load
