摘要 分析了锚杆钻机冲击旋转钻进时,动力头冲击凿岩原理、岩石破碎的外载荷特点及应力分布状况、岩石破碎时的物理过程等;最后使用LS-DYNA有限元分析软件,建立了冲击凿岩系统的有限元模型,对岩石的冲击破碎结果进行仿真与分析,为锚杆钻机的动力头冲击特性研究提供了理论基础。 Analysed the working principle of hydraulic jumbolter, the electronic loads outside of breakstone, stress distribution status, physical process of brokering rocks, established finite element model of hydraulic impact rotating the jumbolter crashing rock-soil system based on LS-DYNA.Analysed the effect of brokering rocks when drill moving forward, providing theoretical basis for impact characteristics research.
