Abstract

The hydraulic vibration system controlled by wave exciter is a mechanic-electric-fluid integration system, and it has high dynamic characteristics. Modeling and simulation for it has come to professional's attention in the field of hydraulic vibration industry, because it is nonlinear and complex. In this paper, a method has been proposed. By using power bond graph method, the bond graph model for it can be established, meanwhile, it is proposed that controlled parameters are considered to join the model, in order to control power flow alternated; and the mathematical model(state equations) of this system can be built according to bond graph theory and controlled relations; then simulation model can be built by using Matlab/Simulink software, the model can intuitively express system's power flow direction and controlled relations. To the question that stiff equation appears easily in model of hydraulic system, we can choose the adapting algorithm offered by Matlab software to obtain the more precise simulation results.
