摘　　要：在ADAMS/Car中建立虚拟样机模型,通过与实车试验数据比较,验证了模型的正确性。把虚拟样机模型导入MATLAB,并定义了减振器控制力输入接口,在MATALB中创建模糊控制器模型,实现了联合仿真模型的建立。进行平顺性联合仿真,结果表明对阻尼器控制后后轴上方左侧座椅的各向加速度有所降低。所利用的联合仿真研究方法为分析车辆平顺性提供了一种新的途径。A multi-body dynamics virtual prototype model was created with ADAMS/Car. The simulation result was compared with the road test. It proved that virtual prototype model is correct and believable. The model was imported to MATLAB and the control part of adjustable damper was defined. The fuzzy control model was built in MATLAB. So co- simulation model was created. After Simulation, it showed that the acceleration of the left chair on the rear axle in the control model was reduced. The co-simulation method is a new way to the simulation of ride comfort.
