| Abstract: | 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. |

| Keywords: | incident wave penetrative efficiency spring-two-mass-lump medel calculation |
