Failure Patterns Analysis of Transmission Tower under Longitudinal Tensions Based on the Finite Element Numerical Simulation

Abstract:

In order to study failure mechanism of the transmission tower caused by longitudinal tensions under icing conditions, with the model of # 43 cup-tower in 500kV Warsaw I line accident segment as for example and the software of large general-purpose finite element analysis, respectively, this paper analyzed their failure characteristics under three conditions that is non-uniform ice-coating, asynchronous ice-shedding and excessive icing,obtaining weak locations. The results will provide reference for the designing work of this type towers in transmission line which is auto-ice designing, enhancement, enforcement, transformation and reconstruction.
