摘要
用断裂力学的理论与方法,对凿岩机钎杆的寿命进行了定量分析,从而提出提高钎杆寿命的一些措施,提供了计算钎杆寿命的一种方法。
The service life of drill-steel for a rock drill is analyzed numerically with the theory andmethod of fracture mechanics.Thus some measures which can be taken for longer drill-steel life are putforward.Additionally a method is presented for calculation of drill-steel life.
