摘　　要：接杆针对冲击能的传递特性影响接杆式凿岩效率，而接头是接杆钎的重要环节，作者利用冲击钻进波动理论和现代控制理论，建立了接杆凿岩接头的ＳＤＭ（Ｓｐｒｉｎｇ－Ｄａｍｐ－Ｍａｓｓ）动力模型，并对接头的能量传递机制进行了分析，为实现接头的优化设计提供了理论基础。The jointed rod drilling efficiency depends to a large extent on the performancecharacteristics that a jointed drill rod has in impact energy transfer. Drill-rod joint is a keypart of the jointed drill rod.The authors has established a SDM(Spring-Damp-Mass)modelof the drill-rod joint in rock drilling process according to the impact drilling wave theory andmodern control theory,The energy transfer mechanism of the drill-rod joint is analysed,lay-ing a solid theoretical foundation for optimization of drill-rod joint design.
