主动横向稳定器降低商用车侧倾的研究

将新式主动横向稳定器安装在中型货画的前轴和后轴，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。

A Study on Reducing Roll Angle of Commercial Vehicles by Active Roll Stabilizer

In this paper, the new type of active roll stabilizers are mounted on the front and rear axle of an experimental medium-duty truck, which are connected to the frame through their hydraulic actuators. The feasibility of reducing roll angle and improving comfort of commercial vehicles by using this type of stabilizer is studied in the paper. A feed-forward control algorithm for activating the actuators is applied to produce an anti-roll moment which suppresses vehicle roll motion. Simulation analyses and vehicle tests showed considerable reduction of roll angle during steady-state-turning and lane-changing. During the straight driving, the stabilizers are free and do not affect the ride comfort.
