中文摘要：
根据国内外空气锤钎头资料，阐述了空气锤钎头在结构、空气锤钎头与岩石互作用、静力学、动力学、水力学以及计算机仿真技术应用等方面的研究现状。空气锤钎头的研究趋势为，开展增强硬质合金齿和双弧度面齿的设计、借鉴物探潜孔钻头开展空气锤钎头的力学分析、钎头的布齿研究、利用现代设计软件对钎头进行研究。
英文摘要：
Based on the analysis of air hammer bit, the present situation of research on mechanics, mechanism of bit and rock mutual impedance, statics, dynamics, hydraulics and the usage of computer simulation on bit are introduced. The research tendency on bit is proposed, which are the design of PDC and double-dome carbide teeth, the analysis of bit mechanics, the bit tooth ＂arrangement,computer simulation software applied on bit research, which can offer the references to the optimal design of the air hammer bit.
