摘　　要：根据凿岩机冲击活塞的特点提出了弹簧双质量理论模型，并对该模型的入射应力与凿入效率进行了电算。电算结果与实验结果有较好的一致性。Penetrative efficiency(the ratio of rock breakage energy to impact energy)hasmuch influence on drilling rate and work efficiency;However, penetrative efficiency is deter-mined by incident wave shape.According to the characteristics of impact pistons of rock drills, a spring-two-mass-lumpmedel is raised.Furthermore,its incident wave and penetrative efficiency are calculated,the re-sults are in accord with the experimental.
