摘要
针对汽车侧翻事故,提出了基于模糊控制策略的主动悬架系统来改善汽车侧翻稳定性的方法,选取车辆悬架左、右侧弹簧的垂向变形量之差及其变化速度作为控制参数,以车辆侧倾角作为防侧翻稳定性的评价指标。建立相应主动悬架的ADAMS仿真模型,通过ADAMS和MATLAB的联合仿真,分析了主动悬架对汽车防侧翻性能的影响。研究结果表明:主动悬架可以有效改善汽车的侧翻稳定性,性能明显优于被动悬架。
To improve automobile side tumbling stability, the active suspension based on fuzzy control is built. Take the difference of the vertical distortion of right spring and left spring of suspension and its velocity as control parameters and roll angle as evaluation index for side tumbling stability of vehicle. Co-simulation with ADAMS and MATLAB is conducted and the results show that the active suspension greatly enhances the active safety of the vehicle and is much better than passive suspension.
