【Abstract】 In order to study the influence of the oil supply pressure on the impact performance of the hydraulic impactor system, a nonlinear model of the gas-liquid combined hydraulic impactor system was established based on the analysis of the working principle and characteristics of the hydraulic impactor system. AMESim is used to simulate and analyze the return acceleration process and the return deceleration process of the hydraulic impactor, and the influence of the system oil supply pressure on the impact performance of the hydraulic impactor is studied. The results show that the system oil supply pressure has an important impact on the impact performance of the hydraulic impactor. The optimal system oil supply pressure of the same type of hydraulic impactor is 19～22 MPa through repeated simulation and optimization analysis. It provides guidance for the design of hydraulic impactor and parameter optimization of hydraulic system.更多还原
