Abstract :
The hydraulic vibration system excited by wave exciter is established. After analysis on Poisson coupling and Junction coupling in excited vibration system 4-eqation dynamics model on liquid flowing, pressure fluctuation and pipe vibration is adopted, and numerical analysis of fluid-solid coupled vibration system excited by wave exciter is carried out by using method of characteristics. The results of numerical analysis show that pressure wave velocity is descending, and vibration periodicity prolongs because of Poisson coupling; at the same time, stress wave velocity of pipe is increasing, and vibration periodicity is shortened. The results of numerical analysis agree with those of experiment.
