摘　　要：运用动力学理论 ,对YDT 31型电动凿岩机冲击机构的结构及其工作原理进行动力学分析 ,建立了机构的一般动力学方程。在此基础上引入电算模拟方法 ,对凿岩机冲击机构的动力过程进行了数值计算 ,讨论了机构特性对性能参数的影响 ,并将理论结果与高速摄影结果进行了对比分析。A dynamic analysis is made of structure and operating principle of a new type percecssive mechanism of YPT31 electric rock drills using dynamic theory, and a general dynamic equation is established for the new type percussive mechanism. On this basis, numerical computation is carried out for the percussive mechanism′s dynamic process by computer simulation. The author discusses the influence of the mechanism on its performance parameters and compares its theoretical results with the results obtained by highspeed photograph.
