A hydraulic damping device is designed in this paper, and the working principle of the whole system and suspension hydraulic cylinder is also analyzed. The system of vibration model based on the power bond graph theo-ry is established. Besides, the state equation as well as control the system damping characteristics through the fuzzy control strategy are also deduced. The simulation model of the hydraulic damping device is obtained by using Mat-lab/Simulink software. After compared with the passive system analysis, it can be seen that the vibration stability of the hydraulic damping device has improved significantly.
