Bond Graph Simulation and Test on the Working Hydraulic System of ZL50 Type Loader
Based on the modeling and simulation software 20-sim developed by Control Engineering Group in University of Twebte in the Netherlands, the bond graph model of the hydraulic system for the working device of ZL50 wheel loader was established. During simulating the model, with the main parameters of the model were set based on the actual test result, which can skip deriving state function and simulate the system directly with the results of pressure response. The simulation results show that this method is feasible and convenience in the application of hydraulic dynamic simulation. Further more, through the test of cylinder pressure when the loader in the practical work, by comparing with the simulation results, which provides a new way in the field of dynamic modeling and simulation for hydraulic system.
