摘　　要：主动悬架对于汽车的稳定性及其重要,本文建立汽车主动悬架模型,利用模糊控制进行振动位移误差的调节,以B级路面和C级路面路面不平度作为输入,评价指标包含垂向加速度、悬架动挠度、胎面动载荷,将模糊控制下的车身舒适性与平稳性进行对比分析。结果表明:加入模糊控制策略后,汽车悬架性能显著改善,表明模糊控制对于车辆平稳性的改善具有一定的有效性。Active suspension is crucial for the stability of automobiles.This article establishes an active suspension model for automobiles and uses fuzzy control to adjust vibration displacement errors.The roughness of B-level and C-level road surfaces is used as input,and evaluation indicators include vertical acceleration,suspension dynamic deflection,and tire dynamic load.The comfort and stability of the vehicle body under fuzzy control are compared and analyzed.The results show that the addition of fuzzy control strategy significantly improves the performance of car suspension,indicating that fuzzy control has a certain effectiveness in improving vehicle smoothness.
