The Feasibility Study for New-Type Forging Flange of in Steel Tower

Abstract

This paper presents a new-type forging flange used in steel transmission towers, that is to forge a same flange and same bolts in large a forging flange, in order to increase the strength and rigidity. This paper seted up finite element models of inner forging flange and outer forging flange. At the same time the article established finite element models of the new-type forging flange and new-type rigid flange used in engineering.The comparative analysis of the results shows that, the new-type forging flanges greatly improved the strength and rigidity of the joints because of the reasonable stress distribution and constraints of deformation.
