Leakage Simulation of the Impactor of Hydraulic Rock Drill

摘要

In order to research the leakage mechanism and influence factors of the hydraulic rock drill, the mathematical model of the leakage is established, and combined with the structure and working principle of the hydraulic rock drill, the impact mechanism dynamics simulation model is built by the AMESim software. Through the analysis of the leakage model, the influence of differential pressure, sealing length and clearance on the leakage is got, the simulation analysis results are consistent with the mathematical model conclusions, and the results have important guiding significance on the clearance selection and the effective control of leakage of the impact mechanism.
