| Abstract: | 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. |
