| 摘 要： | 针对特高压输电线路塔线体系风致响应较大的特点,以某输电塔线工程为原型,按照空气动力学弹性相似准则,设计制作了输电线路塔线气动弹性模型,进行了多个风向角、多个风速下单塔与塔线体系在紊流场中的风洞试验.试验结果表明,对于跨度不大的塔线体系,较低风速下(风速约<20-25 m/s)塔线中塔的加速度要高于单塔,当风速继续增加时,单塔的加速度将超过塔线体系.塔线体系总的风振响应需要考虑塔线耦合作用的影响.

| 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 ... |
