摘　　要：通过MATLAB软件建立基于二自由度主/被动悬架动力学仿真模型,计算出被动悬架簧载质量速度与悬架动行程位移作为主动悬架控制的输入量;半主动悬架采用双模糊控制策略算法,用加权系数分别控制第一主控力与第二主控力在总控制力中的比重;计算结果表明:采用双模糊控制策略算法在对改善悬架的总体性能有明显作用,车身垂直加速度、悬架动行程、俯轮胎动行程性能分别提升28.5%、9.9%、10.3%。The two degrees of freedom active / passive suspension dynamic simulation model is established based on MATLAB software. The passive suspension sprung mass suspension dynamic travel speed and displacement as an active suspe sion control input is calculated. Double fuzzy control strategy algorithm is used in semi-active suspension. The first and second main force in the proportion of total control is controlled by the weighting coefficient. The results show that： a double fuzzy control algorithm plays a significant role in improving overall performance of suspension. Body vertical acceleration, suspension dynamic travel and travel overlooking the tire dynamic performance upgrade by 28.5%, 9.9% and 10.3% respectively.
