NUMERICAL SIMULATION OF DE-ICING PROCESS OF ICED MULTI-SPAN TRANSMISSION LINES UNDER SHOCK LOAD
The numerical models of typical sections of iced multi-span transmission lines are set up by means of ABAQUS finite element software, and the processes of de-icing under impulsive excitations are numerically simulated. The. user material subroutine VUMAT is developed to describe the porous elastic constitutive model of the ice and delete the broken elements identified by tensile failure criterion. A large number of de-icing scenarios are numerically simulated to investigate the effects of various factors, including span length, ice thickness, number of spans and amplitude of shock load, on the rate of de-icing.
