摘要

To investigate the impact of low pressure accumulator to the performance of hydraulic impactor, mathematic model of hydraulic impactor was established. By application of AMESim, The simulation models of hydraulic impactor with low pressure accumulator and hydraulic impactor without low pressure accumulator were obtained. After model calculation, the displacement, velocity of the piston and the return pressure were shown in figures. Rationality of the simulation system was verified by the compare between simulation results and experimental results. The simulation results show that low pressure accumulator can increase the impact energy and frequency of hydraulic impactor in a small degree and reduce the impact of return pressure significantly. Article provides theory basis for the designation of hydraulic impactor.
