Based on experimental test,this paper uses approximate calculation for computing dynamic characteristic parameter of impact mechanism of hydraulic rock drill.According to hydraulic rock drill design parameters and simplifying the motion process of the impact mechanism of hydraulic rock drill as constant acceleration model, the dynamic characteristic parameters has been calculated. This method is simple and clear, and the calculation resultis approximate well with the test. It can be used to analysis and calculate the impact mechanism having a similar structure to meet the needs of engineering design.
