Percussion characteristic analysis for hydraulic rock drill with no constant-pressurized chamber through numerical simulation and experiment

Considering the insufficiency of numerical study on the percussion characteristic of hydraulic rock drill, which restricts the improvement of efficiency and reliability, a coupling model including the impact piston, spool valve, impact accumulator, and connecting pipelines was established taking int...
