Abstract
The lack of research on the double damper system seriously restricted the impact power’s increase of hydraulic rock drills. The structure and working principle of the double damper system are described. The key parameters such as the unloading damping pressure, damping flow, equilibrium position of the damping piston, and double damper clearance are designed. At last, the design method is applied to the YYG170 hydraulic rock drill. Double damper system’s advantages of high efficiency and fast response are verified by simulation.
