摘要
疲劳损坏是导致矿用钻杆接头失效的主要原因之一。以准50的六方形钻杆接头为研究对象,采用Solidworks建立接头主要零部件的三维模型,导入ANSYS对其进行有限元分析。利用42CrMo材料的S-N曲线,得到钻杆接头的疲劳寿命、应力集中分布情况,为合理地使用矿用钻杆和进一步的优化设计、改进结构提供了理论依据。
Joint fatigue damage is the main reason of mine drill string failure. In this paper, the ？50 six square tool joint is taken as the research object. The 3D model of joint main components is built by Solidworks, then the model is imported into ANSYS to make the finite element analysis. The fatigue life and the distribution of the stress concentration of drill pipe joint are acquired by the 42CrMo material S -N curve, which provides theoretical basis for the reasonable use of mining drill pipe, further optimization design and structure improvement.
