Wind tunnel test on suppressing vortex-induced vibrations of steel tubes in power transmission towers

  • 摘要: 为了深入研究输电塔钢管的涡激振动特性,对安装不同设计参数扰流板的输电塔钢管进行了风洞试验。验证了输电塔钢管涡激振动临界风速和最大振幅的预测公式,并得到了扰流板外形、间距、长度、肋高等参数对输电塔钢管涡激振动抑振率的影响规律。在此基础上综合考虑材料成本、制作安装成本和抑振效果对不同设计参数下扰流板的抑振性价比进行了评估,最后基于帕累托最优解法选取了考虑成本后的扰流板最优设计方案,研究结果为扰流板设计参数的取值提供参考。

     

    Abstract: To investigate the effects of spoilers for mitigating vortex-induced vibration (VIV) of steel tubes in transmission towers, a series of wind tunnel tests on steel tubes with various design parameters of spoilers are carried out. The well established formula for predicting the VIV critical wind speed and the VIV maximum amplitude of steel tubes are verified, and the influence of configuration, spacing, length, and height of spoilers on VIV suppression rate are systematically studied. In addition, the material cost, installation cost and vibration suppression rate are taken into consideration for evaluating the cost performance of the spoiler with different design parameters. And the optimal design plan of the spoiler in considering the cost is selected based on the Pareto optimal solution method. Finally, corresponding suggestions on the value of the spoiler design parameters are given for the best control of vortex-induced vibrations of the steel tubes in transmission towers.
