Dynamic Simulation of the Impact Mechanism of Hydraulic Rock Drill Based on AMESim

摘要

Through analysis of the dynamics process of hydraulic rock drill, this paper builds a model of the impact mechanism of hydraulic rock drill with AMESim software, obtains curves of the displacements of the piston and valve core, and gets the pressure of the piston chamber. The dynamic analysis of the results indicates that the model of the impact mechanism of hydraulic rock drill agrees well with the principle of hydraulic rock drill. As a result, this research provides a new theoretical basis and method for the hydraulic rock drill.
