The Galloping Parameters Study of Ice-Coating Transmission Line
In this paper, 3-DOF finite element model for galloping has been built on the basis of form-finding analysis. Fitting formula about aerodynamic parameters has been obtained by wind tunnel test. With the combination of finite element model and aerodynamic parameter, a simulation model of single bundle on 3-span was built. And the response of ice-coating transmission line was calculated with different span, initial attack angle, wind speed, suspension insulator length and initial tension. With the comparison of the calculated results, span, initial attack angle, wind speed and initial tension have direct effect on galloping amplitude, order of the galloping, load on suspension insulator and tension on the midpoint of span. On the contrary, suspension insulator length doesnt have obvious effect on galloping.
