Studies on Galloping of Iced Conductor based on Tower-Line Coupling System-Aerodynamic loads
Based on the second development at the ANSYS computing platform,finite element model of a Tower-Line Coupling system was established.The computational fluid dynamics module (CFX) was used for the numerical simulation of the aerodynamic characteristics of iced conductor.On the basis of the Kaimal spectrum,fast Fourier transform was introduced to prepare the wind speed simulation program WVFS with spatial correlation into consideration,thus generating aerodynamic coefficients of iced conductor at different wind attack angles as well as wind speed time series at tower-line nodes.According to the finite element model of continuous multi-conductors and the aerodynamic force-wind attack angle curve,the explicit integration is applied for numerical solution of galloping of iced conductor.
