Abstract

The studies and experiments of hydraulic wave exciting mechanics play an important role for the development and application of new hydraulic vibrating machine. A new hydraulic wave exciting pattern using water-hammer is proposed, and the hydraulic water-hammer exciting system is built. The pressure-time change rule of the water-hammer exciting system is obtained by experimental research, and the time-domain analysis shows that the periodity of pressure fluctuation is controlled by wave-exciter. Moreover, the experimental results show that the periodic controllable hydraulic water-hammer wave generated by the system can be used as an exciting force. The excitation mechanics on hydraulic water-hammer has been discussed, and a new path is provided for the application of hydraulic vibrating machine.
