摘　　要：通过对冲击凿岩典型系统的波动力学分析,提出了反映冲击凿岩机具波动力学和结构特征的参数α,继而确定冲击凿岩机具的动力学特征参数α和运动学特征参数τ,实现了活塞弹性动力学与刚体运动学的融合,为冲击凿岩机具的概念设计提供了较完整的方法。图2,参9。By the analysis of wave mechanics of typical percussive drilling system of rock, characteristic parameter a, which describes wave dynamics and structure of the percussive drill system, has been presented. The piston elastic dynamics and geostatics will be mixed into the conceptual design procedure by means of mixing motional characteristic parameters a and r of percussive tools. A new mixed dynamic design method of the percussive drill is developed. It will provide a complete method of concept design for percussive drills of rock. 2figs. , 9refs.
