特高压输电塔线体系气弹模型设计与风洞试验
Aeroelastic model design and wind tunnel tests of UHV transmission line system
摘要
Abstract
According to the aerodynamics similar flexibility rule and the feather that the wind induced response of transmission line system is evident,the aeroelastic model of ultra high voltage(UHV) transmission line tower was produced taking the certain transmission project being constructed as the research background. A number of wind directions and various wind speeds over the single - tower or tower - line system in flow turbulence were tested in the wind tunnel tests experiments. The analysis results showed that, the acceleration of the little long span transmission tower -line system became higher than that of the single tower under low wind speed (about ＜ 20m/s ～ 25m/s); when the wind speed continued to increase, the acceleration of the single tower exceeded the acceleration of the transmission tower - line system with the influence of the tower - line coupled effects on the two parts of response necessarily being considered in calculation of the wind -induced dynamic response.关键词
