Abstract 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．
