运用应力波理论和强度设计原理，在几种常用凿岩机的理论载荷谱作用下，对国内钎钢钢种典型工艺下的抗疲劳性能进行了动力响应分析．研究结果表明，钎杆的制造工艺对其使用寿命有重要影响；凿岩机机型应与钎杆的抗疲劳性能匹配
Using the theory of stress wave and the principle of strength design, the dynamic response of anti-fatigue performance of typical domestic brazing steels is analyzed under the theoretical load spectrum of several commonly used rock drill. The results show that the manufacturing process of drill rod has an important influence on its service life. The rock drill model should match the anti-fatigue performance of drill rod
