摘　　要：本文针对某钻铤在使用过程中发生疲劳断裂事故的实际问题进行了分析研究。在线性疲劳累计损伤理论的基础上,采用修正过的曼森–科芬方程对钻铤的疲劳寿命进行估算,进一步通过ANSYS Workbench有限元软件进行仿真分析。结果表明,仿真分析的危险截面与真实情况相符,且其得出的寿命与理论估算基本吻合,为工程设计提供参考。The practical problem of a drill collar fatigue fracture accident occurring in the using process is studied. On the basis of the linear fatigue cumulative damage theory, the revised Manson-Coffin equation is used to estimate the fatigue life of drill collar. Further the finite element software ANSYS Workbench is applied to simulate the analysis. Comparing the results of the analysis, we can conclude that it can be applied in the practical engineering.
