| Abstract: | Using the software ANSYS to take the nonlinear finite element analysis for non-stiffened flange joints frequently-used in gantry of substations.Revealing the characteristic and stress distribution of the flange joint under tensile-bending loads,the bolt internal force of flange joints with different flange plate thicknesses are compared under same load;and the reason that how the flange plate rigidity influences the bearing performance of the flange joints is analyzed. |
