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.

水锤激振试验系统的研究
液压波激振力学的研究和实验对新型液压振动机的开发和应用具有重要意义。提出了一种利用水锤进行水力波浪激励的新模式,并建立了水力水锤激励系统。通过实验研究得到了水锤激振系统的压力-时间变化规律,时域分析表明,压力波动的周期由激振器控制。实验结果表明,该系统产生的周期性可控水力水锤波可以作为激励力。探讨了液压水锤的激励机理,为液压振动机的应用提供了一条新的途径。
