对铸钢空心球节点在不同的轴力和弯矩组合作用下的承载力进行了弹塑性有限元分析,得出了节点的塑性发展过程及极限承载力;并基于冲切面剪应力破坏模式推导了轴力和弯矩共同作用下的铸钢空心球节点承载力计算公式。
The elasto-plastic finite element analysis of the bearing capacity of hollow steel ball joints with different axial forces and bending moments is carried out, and the plastic development process and ultimate bearing capacity of the joints are obtained. Based on the failure mode of shear stress of die-cut surface, The bearing capacity formula of hollow steel ball joints under axial force and bending moment.
