Comparative Analysis of Dynamic Characteristics under Two Iced Conductor Galloping Models
Applied Mechanics and Materials, 2011Considering strongly nonlinear characteristic of iced conductor rotating around its center of mass in the wind-deviation plane, two dynamic equations are constructed by using Den. Hartog criterion and O. Nigol criterion, and galloping characteristics between them are studied, which can provide references for constructing correct iced conductor ...

Galloping Characteristics of Conductor Accreted with Crescent-Shaped Ice
Applied Mechanics and Materials, 2012Accounting for the disastrous phenomena of ice-accreted conductor galloping, wind tunnel tests of LGJ630/45 conductor accreted with crescent-shaped ice are conducted. Based on the test results, conductor galloping is simulated by employing the PCL language of ANSYS commercial software package and then the influences of span lengths as well as free ...

Investigation into galloping characteristics of iced quad bundle conductors
Journal of Vibration and Control, 2014A nonlinear finite element method for galloping of iced bundle conductor transmission lines is presented. Wind tunnel tests for galloping of quad bundle conductor segments with crescent-shaped and sector-shaped ice models were carried out, and validity of the finite element method is demonstrated by the consistency of the galloping responses ...
