Abstract
Hydraulic rock drill with no constant-pressurized chamber is widely used now. The performance of the hydraulic impact mechanism directly influences the overall performance of the rock drill. Dynamic simulation and test research of the impact mechanism were carried out. Dynamic simulation is realized by numerical calculation based on the mathematical model. Two types of hydraulic rock drill YYG138 and YYG150 are tested on the horizontal stand. The numerical results are basically consistent with test results.
