Chat OnlineThis paper aims to determine the optimal design parameters for percussive drilling systems considering the bit-rock interaction. First the motion dynamics of a bit impacted by a dropped piston are modeled by impact stress propagation and a rock-breaking mechanism representing the penetration resistance coefficient and unloading constant. Next the damping vibration behavior of the bit is
