中文摘要：

回声钻是一种新技术，仍然在实验室阶段。它有大潜力改进岩石破碎效率。我们分析了泛音颤动在岩石中激动的不变的机械颤动的振幅频率特征，一台仪器被造完成岩石的高频率颤动。在回声钻的穿入(ROP ) 的率上的岩石 drillability，旋转速度，刺激频率，和另外的参数的影响被分析。结果证明岩石 drillability 随刺激频率的增加减少了。当与一项大尺寸练习钻咬了时， ROP 与刺激频率增加了。ROP 在岩石的反响的频率到达了最大的价值。当没有颤动在岩石上被使用并且当泛音颤动被使用时，指数地近似增加了时，小点的 ROP 以旋转速度线性地增加了。另外，岩石的反响的频率在岩石破碎的过程期间正在变化以便完成岩石的需要的回声，决定适当泛音颤动刺激频率是必要的。

英文摘要：

Resonance drilling is a new technology, still at the laboratory stage. It has great potential to improve rock fragmentation efficiency. We analyzed the amplitude-frequency characteristics of steady- state mechanical vibration excited by harmonic vibration in rocks and an apparatus was built to achieve high fi＇equency vibration of rock. The influence of rock drillability, rotary speed, excitation frequency, and other parameters on the rate of penetration （ROP） in resonance drilling was analyzed. The results show that the rock drillability decreased with an increase in excitation frequency. When drilling with a large size drill bit, the ROP increased with excitation frequency. The ROP reached a maximum value at the resonant frequency of the rock. Tile ROP of the bit increased linearly with rotary speed when no vibration was applied on the rock and increased approximately exponentially when harmonic vibration was applied. In addition, the resonant frequency of the rock was changing during the process of rock fi＇agmentation, so in order to achieve tile desired resonance of the rock, it is necessary to detemaine an appropriate hamlonic vibration excitation frequency.
