摘要
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;
Based on stress wave theory and strength design principle,the dynamic responses of fatigue strength of different rod steel under typical technological process to theoretical load spectrums of several usual rock drills are discussed. The results show that manufacturing method of a drill rod has important effect on its life and rock drill type should fit to the fatigue strength of the drill rod which is used in it.
