Research On Valve Operating Characteristics Of Rotary Valve Hydraulic Vibrator

Vibration exists widely in life and engineering practice, vibration mechanics are being continuously developed along with the progress of science and technology. People begin to make use of vibration more and more, tens of thousands vibration machine appear. Vibration is one of them; there are numerous scholars and organizations do research on it, a large number o research and experiment show that vibration aging has the advantage of processing quickly obvious effect energy saving and environmental protecting etc.The main content of this article is introducing the structure and principle of the vibration table do analyses and research on it. Mainly discusses the vibration table structure and principle, the dynamic characteristics of the whole simulation, and the key parts of the rotary valve shaft modal analysis and rotary valve fluid analysis. The paper altogether divides into six chapters; the main content is as follows.The first chapter presents the definition of vibration and development history, the harm of vibration and vibration utilization, vibration aging principle and process and realizes the vibration of the different ways and contrast, different forms of hydraulic vibration.The second chapter presents the hydraulic vibration table composition and working principle, introduced the rotary valve and vibration cylinder, and did the research on rotating valve flow area.The third chapter using simulation software of hydraulic system, and simulation that system parameters affecting relations between and discusses the influence of accumulator and line to the system.The fourth chapter did modal analysis using finite element analysis software ANSYS on system key components rotary valve shaft, get the first six order natural modal and vibration mode diagram, provide guidance for the shaft dynamic design.The fifth chapter did fluid simulation on internal flow field of the rotating valve, the same set up different boundary conditions of the latter and the latter in the same set under different boundary conditions are simulated respectively to strengthen counter rotating valve flow field in the understanding, rotary valve for the optimization and improvement to provide the reference.The sixth chapter is the conclusion and prospect of this work was summarized and the further research was proposed in order to in this paper on the basis of further research.
