摘　　要：运用EASY5建立了阻尼可调减振器模型，运用机械系统分析软件ADAMS建立了悬架的机械系统模型，运用MATLAB建立了基于模糊算法的控制模型，从而实现半主动悬架的建模和联合仿真。结果表明，基于模糊算法的半主动悬架能够很好地降低车辆的振动，提高车辆行驶的平顺性；同时表明联合仿真在研究半主动悬架技术上是可行的，为机电液一体的复杂系统的建模和仿真提供了新的思路。Damping- adjustable shock absorber model is built with EASY5 software, and mechanism model of suspension system is built with ADAMS software and control model based on fuzzy arithmetic is built with MATLAB software. Accordingly, the modeling and co-simulation of semi-active suspension are achieved. The simulation results show that semi-active suspension that based on fuzzy control arithmetic can reduce vehicle vibration and improve vehicle ride comfort characteristics. Furthermore, simulation results prove the feasibility of co-simulation to research semi-active suspension technology, and offer a new idea for modeling and simulating of complex system that integrated mechanism, electric and hydraulic.
