Abstract
Abstract—Submitted to wind induced vibrations, overhead
conductors are vulnerable to fatigue damage, especially at
restraining fixtures such as the suspension clamp. This paper
proposes an efficient finite element modeling approach providing
a full 3D representation of both the conductor and suspension
clamp. Validation based on experimental data shows the
precision of the approach. An in-depth model response analysis
also demonstrates its ability to describe inter-wire and
conductor-clamp contact interactions. Finally, a study of
conductor stress distributions reveals that in critical regions,
conductor wires mostly sustain alternating bending loads.
