Accumulator To Reduce The Hydraulic Drive System Hydraulic Shock Pilot Study

Mechanical drive system is gradually replaced by the hydraulic drive system in construction mechanical vehicle. The traditional mechanical transmission can not solute the fluctuations and shock of load. Hydraulic drive system can reduce the hydraulic shock impact on the efficiency of the whole machinery by the different ways.According to the simplify analysis of the hydraulic drive system, two different mathematical models which are not added storage devices and added storage devices in the hydraulic drive system are recommended.According to the two mathematical models, paper dynamically analysis the hydraulic drive system.The correlate analysis of dynamic simulation and test result shows that adding storage devices is one of the effective ways which can reduce the hydraulic shock and increase energy utilization. The purpose of study is that by analyzing the hydraulic drive system by the use of storage devices to absorb and reuse energy of hydraulic shock and fluctuations load, paper give the program of rational allocation of storage devices in the hydraulic drive system.
