Nonlinear numerical model with contact for Stockbridge vibration damper and experimental validation

Abstract: The Stockbridge vibration damper is widely used in overhead transmission lines to reduce Aeolian vibration. Although a linear analytical model has been developed to interpret characteristics of the vibration damper, a much more detailed model is needed to investigate how the nonlinear factors of the structure affect its vibration characteristics. The paper presents a full-scale finite element model of the Stockbridge vibration damper, in which contact conditions are taken into account using the linear perturba… Show more

“…A full-scale nonlinear finite element model based on 3D solid elements has been recently developed by Luo et al [22]. The 3D finite element approach allows introducing a detailed model for the local contact conditions between the wires of the messenger cables as well as between the clamp and the messenger cable, allowing appreciating how these complex local phenomena play a key role in the determination of the overall dynamic characteristics of the Stockbridge damper.…”

“…The damping mechanism is observed as the vibrations of the conductor are transferred to the Stockbridge damper, and the energy of the conductor is imparted to the oscillating counterweights [6], [7]. The symmetric Stockbridge damper exhibits two resonant frequencies while the asymmetric Stockbridge damper has four [8], [9]. Conventional mathematical models of the Stockbridge damper assume the system to be a 2 DOF system [10], [11] with the counterweight to be a lumped mass and the messenger to be a massless beam.…”
