Modeling and Simulation of Hydraulic System of the Working Device of the Wheel Loader Based on Power Bond Graph
Based on the working principle of the hydraulic system for the working device of ZL60 wheel loader, the power bond graph of its hydraulic system is established by using the power bond graph method under the different working conditions. The power dynamic equations of the system is written out according to the established power bond graph and the Simulink simulation model has been established under the bucket backward operating condition on the basis of the power dynamic equations of the system. This simulation will be carried out by Setting the simulation parameters of the hydraulic system, applying the Simulink software and compiling the M function file. Through these studies, the performance curve of the hydraulic system can be obtained.
