| 中文摘要:采用有限元分析和正交试验相结合的方法对反井钻井用大直径钻杆的接头螺纹参数进行了优化研究。研究结果表明，外螺纹小端大径、锥度、牙侧角和锥部长度等参数对接头螺纹强度有显著影响，得到了各参数作用的主次顺序和不考虑交互作用条件下各参数的最优值。 |

| Abstract:The optimization study on parameters of a large diameter drill pipe joint thread used in mine shaft rising boring is conducted through combining the orthogonal experiment with the finite element theory in this paper. The study results show that small end outer diameter of the screw thread, the taper, side angle of the thread and length of the screw thread etc. have a significant impact on the strength of the thread, the significance order of these parameters on the thread strength and the optimal value of the thread without considering the interaction of these parameters are obtained. |
