| 摘 要： | 以规划中的世界第一高塔--舟山大跨越输电塔为工程背景,在以往工作的基础上,针对塔线耦合体系背景响应与共振响应各自的特征,进一步研究了塔线体系风振响应的频域简化分析方法.通过与单塔风振响应的比较,明确了塔线耦合作用对两种响应分量所造成的不同影响.与时域方法计算结果的对比表明,采用频域分析法,不仅可以获得准确的风振响应,同时提高了求解的计算效率.以简化分析法为基础,选取粘弹性阻尼器为被动耗能装置,采用多目标优化的混合遗传算法计算得到了塔线体系的风振控制方案,并通过理论计算与气弹模型风洞试验对该方案的风振控制效果进行了验证. |

| Abstract: | The tallest transmission tower in the world,which is a part of the ZhouShan long span transmission line system,is studied.According to the different features of the background response and resonant response,a simplified frequency-domain analysis method on the wind-induced dynamic response of the tower-line coupled system is researched based on the previous study.Compared with the single tower,the different influence of the transmission line to the two parts of the tower-line system's response is analyzed.Th... |
