摘　　要：基于螺栓连接中螺纹轴向力产生机理,介绍了螺纹轴向载荷分布特点以及螺纹副承载分布的解析方法和有限单元法。利用有限单元法,建立螺纹连接的轴对称CAE分析模型,研究螺纹旋合圈数对螺纹轴向力分布的影响规律,并将仿真结果与解析对比分析,以验证有限元模型的可靠性,同时对螺纹副旋合长度设计提供指导。Based on the mechanism of thread axial force in bolt connection,this paper introduces the characteristics of thread axial load distribution and the analytical method and finite element method of load distribution of thread pair.By using the finite element method,the axisymmetric CAE analysis model of screw connection is established,and the influence law of screw number on the axial force distribution of screw is studied.The simulation results are compared with the analytical solution to verify the reliability of the finite element model,and provide guidance for the design of screw length of screw pair.
