摘　　要：通过500 kV变电构架刚性法兰在拉弯荷载作用下的研究,应用有限元软件ANSYS分析法兰盘的厚度对刚性法兰连接节点刚度的影响。对有限元结果中典型节点的荷载-位移曲线进行了比较,结果表明:在满足承载力且螺栓的规格、型号都一样的条件下,法兰盘的厚度对刚性连接节点的轴向和弯曲刚度有影响,而对剪切刚度没有影响。Based on the study of the rigid flange in power-transformed frames（500 kV） under tension and bending,the influence about the thickness of flange to the rigidity of rigid flange joints is analyzed by an application of the finite element software ANSYS.According to the contrast with the load-displacement curves of typical joints in the results of finite element,it is shown that the thickness of flange has an impact on the axial and bending rigidity of rigid flange joints under meeting the bearing capacity as well as the same specification and type of bolt,but has no impact on the shear rigidity.
