为研究半挂汽车列车的行驶稳定性受侧风干扰的影响，采用TruckSim软件，建立其动力学模型和侧风模型。在不同风向、不同风速以及不同车速条件下，仿真分析整车在阶跃转向输入下侧倾角、横摆角速度和牵引销转角等的响应；得到了稳定行驶的风速及车速的临界值。侧风风速超过临界值，挂车首先发生侧翻；车速超过临界值，整车进入严重折叠甩尾和侧翻等不稳定状态。仿真结果表明：对阶跃转向工况行驶的半挂汽车列车而言，逆向侧风比顺向侧风的影响更大，加剧了半挂车的侧倾。该结果可对半挂车侧向风稳定性提供参考和借鉴。

A vehicle dynamics model and a cross-wind model were constructed using TruckSim software to study the stability of a tractor semi-trailer in cross-wind. Digital simulations were carried out at different wind heading angles, wind speeds and vehicle speeds with step steering input to analyze different vehicle responses of the roll angle, the yaw rate and the hitch angle and then to obtain the critical vehicle speed and critical wind speed for the tractor semi-trailer with stability driving. The trailer turns over first when the wind speed is more than the critical value. The tractor semi-trailer turns to be drifting, rollover and unstable seriously when the vehicle speed is larger than the critical value. The analyses show that the effect on the tractor semi-trailer with step steering in a counter direction cross-wind is stronger than those in a positive direction cross-wind. The results can provide stability analysis references for tractor semi-trailers in cross-wind.
