Abstract
This paper used the power bond graph method to establish hydraulic system dynamic model for Jet deflector, and derived the equation of state. Simulation of the dynamic characteristics of the hydraulic system is achieved in Matlab/Simulink environment. The delivery pressure of hydraulic pump, the hydraulic cylinder without rod gun pressure, the piston rod speed and other parameters on the dynamic response of the system were analyzed. The simulation results show that the power bond graph method has characteristics of convenient, intuitive and accurate to model and simulate the hydraulic system.
