Analysis of Influencing Factors of the Ice Shedding Vibration on Iced Transmission Lines. Issue 4 (January 2021) - Zhang, Long
Abstract: In order to study influencing factors of the ice shedding vibration on iced transmission lines. Based on the principle of nonlinear finite element analysis, the influences of the modal of conductors, the quality of the ice on ice shedding vibration response of transmission lines was analyzed by means of changing the density of transmission lines. The results show that the simulation method is reasonable and accurate. The worst condition of ice shedding on transmission lines depends on its basic vertical vibration mode. the relationship of the vibration displacement with the mass ratio of iced transmission lines both present the nonlinear proportional law.
