冲击式钻机的一个重要声源就是钻杆的弯曲振动。本文提供了供给系统的能量有多少转化为钻杆弯曲能的理论研究。研究结果表明,大约10％的入射应力波能转化为弯曲能。对于带有可拆卸钻头系统,弯曲能可能会少一些。重量较大的活塞能减少弯曲能量。 An important source of percussive drilling rigs is the bending vibration of the drill pipe. This article provides a theoretical study of how much of the energy supplied to the system can be converted into the bending energy of the drill pipe. The results show that about 10% of incident stress waves can be transformed into bending energy. For systems with a detachable drill, bending may be less. The heavier piston reduces the bending energy.
