Simulated Study On Reducing The Hydraulic Accumulator In The Starting Vibration Of Vibration Compactor

In this paper, hydraulic impact that caused by the hydrodriving vibration compactor in the course of the starting vibration and the measures of reducing the hydraulic impact were studied. On the basis of analyzing the reason that produce hydraulic impact,the dynamics of mechanical of vibration compactor and dynamics of vibration hydraulic system were analyzed, the mathematics model of vibration hydraulic system was simulated and its output models for pressure and flow were deduced. On studying the impact reason the starting vibration of hydraulic impact questions are found ,and search solving measure. For press system to carry on dynamic state analysis towards rising to flap to pound at the bane result in and pressing the vibration round of hydrodriving vibration compactor to learn into the action to the vibration analyze, folio type the vibration liquid of the back track, build up a liquid to press calculation model that pound at pressure value. In order to decreasing hydraulic impact, the principle is analyzed to eliminate or increase hydraulic impact by means of changing eccentric lump structure to cut down the inertia force of starting, changing the pressure of pilot electromagnetic relief valve and changing the parameters of accumulator. Imitate true model through the mechanical system of the establishment vibration, be to kinetics and dynamics characteristic of mechanical system carry on accurately imitating a true calculation. Build up the electromagnetism overflows to flow valve and change to imitate true model toward the valve and press vibration system to carry on to the liquid certain under the work condition of imitate a true research.. Do not add an accumulator and add an accumulator to the vibration system ability machine under two kinds of different circumstances, the non- line form dynamic state of the system model, and carried on to this system analysis. Finally, a simulation research about the means of relief valve to reduce hydraulic impact is carried out, which prove the founded prove founded mathematics model. Also, some pending coefficients are amended and the optimum pressure of relief valve is determined. At the same time, a simulation research about the means of accumulator to decrease hydraulic impact is carried put, in which the optimum primitive capacity of accumulator was determined.
