Analysis of fluctuation mechanics for excited vibration system by pressing transient flow

In this paper, the fluctuation mechanics produced by pressing transient flow in a pipeline system and its propagation character have been analyzed firstly, and then excited vibration system by pressing transient flow has been calculated by classical hydraulic fluctuation equation, in which the controlled principle of pressure and fluid velocity are researched. After establishing excited vibration test system by pressing transient flow, the parameters such as pressure, acceleration and amplitude of vibration at different measuring point in various working condition are measured and analyzed by advanced signal processing technology. The results from theory and test prove that amplitude of pressure, vibration frequency and displacement, velocity of excited vibration system by pressing transient flow are fully controlled and regulated by setting frequency of wave exciter and system pressure.
