Abstract

Abstract: In order to better understand effects of different anti-galloping fittings arrangements, the nonlinear vibration properties of Shuangxin 5465 line and anlong 5466 line are analyzed theoretically through galloping equations with curved beams and anti-galloping fittings arrangements. Performances of two fitting scheme, namely spacers only and double-spacer pendulum damper combination, are evaluated. Results show that both arrangements have ability to suppress line galloping. However, combination of two schemes are more effective.

Key words: damp spacer, double pendulum damper, galloping of iced overhead transmission line, overhead transmission line, nonlinear dynamics
