本文讨论了管道弯头的力学简化模型——弹性抗弯铰在管系结构分析中的应用,给出了考虑结点柔性的直管单元的单元刚度矩阵和等效结点载荷。与传统的弯管单元相比较,文中给出的方法可以减少单元和结点数目,节约计算机内存空间和计算时间,并能得到工程上较为满意的结果。 This paper discusses the mechanics simplified model of pipe elbow - the application of elastic bending hinge in the analysis of pipe structure, and gives the unit stiffness matrix and equivalent node load of straight pipe unit considering the flexibility of the joint. Compared with the traditional elbow unit, the method given in this paper can reduce the number of units and nodes, save computer memory space and calculation time, and can get satisfactory results in engineering.
