摘　　要：针对车辆平顺性与安全性问题,该文提出了一种基于力输出的新型电液比例控制半主动悬架系统。并建立了1/4半主动悬架模型,应用变论域模糊控制策略进行了AMESim和Simulink的联合仿真,结果表明经过变论域模糊控制策略后的1/4半主动悬架较被动悬架簧载质量加速度降低了34.3%;悬架动挠度降低了7.3%;非簧载质量加速度降低了10.6%。For vehicle ride comfort and safety problems, A new type of electro-hydraulic proportional control semi-active suspension system based on force output is put forward. 1/4 semi-active suspension model is established, Do the joint simulation analysis with AMESim and Simulink. The simulation results show that variable Universe Fuzzy Control for Semi-active Suspension Compared with Passive suspension, The sprung mass acceleration was reduced by 34.3%; The suspension dynamic deflection was reduced by 7.3%; The mass below sprung acceleration was reduced by 10.6%.
