Analysis of the Effect of wind Loads on the dynamic response of the Suspended Crossing-Tower Auxiliary System

Abstract

The operational impact analysis of Crossing-tower Auxiliary Fittings System is a performance impact analysis of the operational stability and performance indicators of the line and auxiliary towers under a variety of environmental conditions for the long-term operation of the auxiliary crossing-tower system. In this paper, the suspension type auxiliary tower fitting system is divided into two types: the hard rod connection and the soft line connection. The influence of the arrangement of the wind pendulum, ice coating and anti-vibration hammer on the mechanical performance is considered. At the same time, the influences of the length of the bridge, the span and sag of the ground wire on the displacement and stress-strain of the bridge over the tower are analyzed. On this basis, it lays a certain theoretical basis for the structural optimization of the suspended tower auxiliary system.
