摘　　要：采用通用有限元软件ANSYS对多组不同尺寸的焊接空心球节点的节点刚度进行了有限元计算和分析,并利用统计分析软件SPSS对大量计算结果进行回归分析,从而在弹性范围内建立了轴力柔度系数和弯曲刚度系数与球径、球壁厚、杆径的相关关系式。In this paper, weld hollow spherical joints are analysed and computed by finite element program ANSYS in many groups of different size. And then we get the relative formula which is about the axial flexibility coefficient and flexural stiffness coefficient expressions with parameters： joints＇diameter and thickness, members＇ diameter by using the statistical analysis software SPSS to make regression analysis on lots of results.

关 键 词：节点刚度 有限元分析 回归分析
