The current vibration modes, whether inertial vibration or hydraulic vibration, have some problems such as large power consumption and low energy utilization rate. A new low energy hydraulic excitation mode is presented. This mode takes the high-pressured pipe as the new excitation source. Periodic pressure pulsation generated by wave exciter makes the pipe vibrating. The vibration mode of pipe with fluid-structure interaction is established and solved with numerical method. The modal analysis and the simulation of the vibration have been carried out. An experimental platform is built to verify that the new hydraulic vibration can be exploited.
