Abstract
In order to study the mechanism of the breeze vibration of transmission lines, based on the non-linear model of Scanlan's experience, the finite element motion equation of the transmission line's breeze vibration is derived, and the dynamic solution is carried out. The results show that the parameters of Scanlan vortex force have a significant influence on the stable amplitude of the breeze vibration of transmission lines. Due to the neglect of the bending stiffness of the cable elements, the finite element calculation results of the cable breeze vibration are slightly less than the energy balance method, and as the wind speed increases, the error increases gradually; when the wind speed is 3m/s, the frequency of the wire vortex-induced vibration is 30Hz, which is consistent with the calculation of the Stokehal number.
