将新式主动横向稳定器安装在中型货车的前轴和后轴,通过液压缸与车架连接。本文研究了该稳定器对降低车身侧倾和提高舒适性的效果。仿真分析和实车试验表明,采用前轮转角前馈控制方法,汽车转向时,稳定器产生反侧倾力矩,大幅度地降低车身侧倾。汽车直线行驶时,稳定器处于自由状态,对舒适性不产生影响。 The new active transverse stabilizer is mounted on the front and rear axles of mid-size trucks and connected to the frame via hydraulic cylinders. This article investigates the effect of this stabilizer on reducing body roll and improving comfort. The simulation analysis and actual vehicle tests show that when using the front wheel angle feedforward control method, when the vehicle turns, the stabilizer produces anti-roll moment, which greatly reduces body roll. When the car is driving in straight line, the stabilizer is in a free state, which has no influence on the comfort.
