高耸格构式塔架风荷载试验研究

Research for the Wind Force on High-Rise Latticed Tower

按照空气动力弹性相似准则 ,设计制作了某高压输电线路终端塔全塔气动弹性模型 ,并按响应相似原则模拟了柔性输电导线 ;在大气边界层风洞中进行了风荷载及风振响应的试验研究 ,获得了塔架体型系数、风振响应和风振系数等设计数据 。

An aeroelastic model for a UHV power transmission tower and its conductors was designed according to the law of similarity and tested in an atmospheric boundary layer wind tunnel. Some important information useful in designing such as type coefficients of the tower, response of wind induced vibration and coefficients of wind induced vibration was obtained. The influence of conductors on the vibration of tower was also discussed.
