Investigation Into the Galloping Characteristics of Multispan Iced Covered Conductors

open access: yesIEEE Access, 2022
A full multispan two-degree-of-freedom (2-DOF) iced covered transmission line model is presented. Taking multispan conductors as the research object, based on the Hamiltonian principle, a nonlinear galloping model of multispan conductors considering the influence of insulator strings is established, and its galloping equation is derived.

Damping capacity of materials and its effect on the dynamic behavior of structures. Review

open access: yesEnergy Reports, 2021
Damping is very important when studying the vibrations of bridge structures. A distinction is made between structural damping and damping due to internal friction in the material.

The interaction between flow-induced vibration mechanisms of a square cylinder with varying angles of attack [PDF]

open access: yes, 2012
This study examines the influence of angle of attack of a square section cylinder on the cylinder’s flow-induced vibration, where the direction of the vibration is transverse to the oncoming flow.
