Bond-graph modeling approach to a hydraulic system was discussed.The bond-graph model of damper test-bed's hydraulic system was built according to the power bond graph theory.This model's dynamic simulation results,such as the velocity response and pressure response,were indicated in the environment of 20-sim software.Simulation results show that bond-graph modeling approach is feasible and correct.Further more,the Simulink model was built for a result contrast.Contrastive results prove that the modeling method is reliable.So,the whole result provides a new way in the field of dynamic modeling and simulation for hydraulic system.
