摘要
为了提高车辆的抗侧翻能力,设计了一种主动横向稳定器,基于MATLAB/Simulink中建立了8自由度整车动力学模型,采用PID理论进行控制,并以紧急转弯和绕桩试验两工况进行仿真分析。结果表明:主动稳定器能够大大降低车辆转向时的车身侧倾,并且能够相应地降低车轮横向载荷转移率,对提高车辆的抗侧翻能力与操稳性具有很好的效果。
In order to enhance the anti-rolling of vehicle,a kind of active anti-roll controller( ARC) is designed and an eight-DOF dynamic model is built up based on the platform of Matlab / Simulink. The ARC is controlled with PID theory. Two kinds of typical cases including turn in emergency and slalom testing are simulated and the simulations prove that the active anti-roll controller will greatly reduce the roll angle of vehicle when cornering. It can also reduce the transfer rate of lateral load and have a good influence on the operability and stability of the vehicle.
