论文名称：Modeling and simulation of the hydraulic exitation system based on the power bond graph  

摘要：The article introduces one kind hydraulic fluctuation excitation installment which produces the exciting force through the shock exciter compulsion port. Basing on the synopsis system's composition and work principle, the hydraulic fluctuation excitation installment simulation experiment system is established in the laboratory, simultaneously the power bond graph and the control theory is applied to establish this experiment system's mathematical model, and it has been carried on the simulation analysis using the Matlab/Simulink simulation software to the system. The result of simulation indicates: The hydraulic fluctuation excitation equipment which based on the shock exciter compulsion port composition has fully used the hydraulic shock-wave of the compulsion port and shock exciter valve port instantaneous opening and shutting, therefore this system's efficiency has the more distinct enhancement than the general hydraulic fluctuation excitation system.
