摘　　要：以气动肌肉作为新型执行器 ,创建基于 1/4悬架模型的汽车主动悬架系统。并运用Matlab中的Simulink模块库建立此系统的仿真模型 ,着重讨论仿真建模以及仿真过程中所遇到的困难 ,诸如气动肌肉迟滞特性的实现、高频分量对仿真结果的影响等问题。经对系统机理模型的适当变换处理 ,促进了仿真系统的稳定。利用获得的仿真模型对气动肌肉主动悬架系统的动态特性进行仿真研究 。The paper presents an active suspension experiment system with pneumatic artificial muscle as actuators according to the 1/4 suspension mechanism model. We employ the Matlab with Simulink to build up the simulation model of the system, emphasizing on the difficult points such as the realization of hysteresis of pneumatic artificial muscle, the disturbance of high frequency components to the simulation system and so on. Under the simulation based on the optimized simulation model, results reveal the dynamic character of pneumatic artificial muscle, and justify the optimized simulation model for further study of such an active suspension.
