Based on the example of the Chuxiong Yunnan-Huidong Guangdong ±800 kV transmission line system,this paper investigates the effect of the jumping induced by the ice-shedding with four cases,and analyses the vibration controls under six installing cases of the lead viscoelastic dampers by using the nonlinear time history analysis method.

Based on a certain project, the lead viscoelastic dampers with lead double layers of glue elastic material and inside are used to control the wind performance.

Based on the example of Jindongnan-Nanyang-Jingmen 1000kV transmission lines system,jumping responses induced by ice-shedding in four cases are investigated,and the vibration controls in six installing cases of lead viscoelastic dampers using the nonlinear time history analysis method are studied.

Calculating models of lead viscoelastic damper;

In this paper, the principle configuration and characteristicses of the mixed lead viscoelastic damper are introduced.

Influence of boundary conditions on dynamic parameters of viscoelastic damper;

Energy dissipation effect analysis of the tall building equipped with lead-rubber dampers;

Additionally,lead-rubber dampers are installed on head of tower to control the vibration induced by broken wires.

Small and light lead-core rubber damper(LRD) can effectively control structural aeolian vibration.

Using Yun-Guang ±800 kV UHV DC transmission project as background and combining its engineering characteristics,the aeolian vibration response of transmission tower controlled by lead-core rubber dampers is studied.
