Impact Of Wind-Induced Vibrations On Aluminum Conductor Fatigue: A Novel Testing Approach

Vetor
In transmission lines, wind-induced vibrations, like high-frequency wind vibrations and low-frequency galloping phenomenon, can cause fatigue damage and failure, particularly in aluminum conductors, which have greater flexibility.

Numerical Analysis of Conductor Galloping Limitation by Oscillation Frequency Detuning

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2009
A numerical method has been developed for calculation of conductor oscillations at the moment of galloping that takes account of pendulum  oscillation dampers in the form of eccentric loads.

A third-order characteristic-based-split finite element scheme of Spalart–Allmaras model and its application to flow past crescent iced 4-bundled conductors

Advances in Aerodynamics
The one-equation Spalart–Allmaras (SA) model is employed to close the Reynolds averaged Navier–Stokes equations (RANS equations), and research on turbulent numerical algorithm is carried out.

Study on the prediction of aerodynamic coefficients for crescent-shaped ice-accreted conductors using a BP neural network

AIP Advances
This paper presents a nonlinear mapping prediction model for aerodynamic coefficients of ice-accreted conductors, which is established using a BP neural network. The model integrates experimental data and computational fluid dynamics numerical simulation
