NUMERICAL MODELING AND SMALL-SCALE EXPERIMENTAL SIMULATION OF ICE SHEDDING PROPAGATION ON BUNDLED CONDUCTORS
Ice shedding propagation on bundled conductors is simulated numerically and experimentally. A numerical model was built using a commercial finite element software ADINA, whereas experiments were carried out on a small-scale setup in laboratory. These models simulate the propagation of ice shedding from one cable in a twin bundle together with the resulting vibration. The calculated and measured parameters are time histories of vertical and transverse vibrations of the cable and time histories of the angle of bundle rotation in the middle of the span when the number of spacers is varied. The numerical model is validated by comparing the computed and measured results. This model may easily be modified to simulate ice shedding propagation and the induced vibration on bundled conductors in real-scale transmission lines.
