摘　　要：根据液压凿岩机活塞的运动规律,建立了活塞运动微分方程,推导了其运动学参数的表达式,研究了液压凿岩机活塞与缸体间隙密封段的能量损失,建立了其数学模型。通过分析指出,应存在使能量损失最小的一组封油长度值。According to the motion rule of piston of hydraulic blast hole drill, the differential equation of motion of piston is set up and the formula of the kinematics parameters is inference. The energy wastage in sealing gap between piston and cylinder is studied and its mathematic model is set up. It shows that there is a group of sealing length with the minimum of energy wastage.
