【摘要】 根据套管螺纹接头的结构和受载特点,基于接触问题的有限元混合法和面向对象的程序设计思想,建立了套管接头螺纹旋合接触的有限元分析模型,编制了相应的有限元分析程序,并以此对3种载荷条件下载荷在各螺牙上的分布进行了分析研究,结果表明,载荷分布的不均匀性对套管螺纹接头的连接性能有重要影响,从而为套管接头螺纹的合理设计提供了基础更多还原

【Abstract】 A finite element mothod is developed that makes use of object oriented programming technology whereby attention is given to the contact and mixed conditions. The character of load distribution in the casing thread is studied in connection with interference fitting, pull force and inner pressure. Non informity of load can significantly affect the connection behavior of thread joints.更多还原
