Abstract
Through analysis on the structure and the opearation mechanism of the hydraulic rock drill,the dynamic model of its impact mechanism is built with AMESim,and the displacement variation curves of the piston and the reversing spool as well as the pressure variation curves of the piston chambers are obtained.The simulation results show that the simulation model has the same operation status with the actual operation,which offers new references and method for the design and the study of the hydraulic rock drill.
