Firstly, the finite element models of dump-type transmission tower and SMA damper are built with ANSYS software, the wind load is simulated with Matlab software, and the time history samples of random fluctuating wind load are obtained using the linear auto-regressive filter law. Then, six layouts are proposed based on the working principle of damper and the structure of the tower. Finally, wind-induced vibration transient response simulation is performed for each different scheme. The responses of SMA dampers on the displacement and the acceleration of the controlled nodes are compared with each other. The results indicate that the SMA damper can suppress wind-induced vibration, and that different layouts have different control effects. Installing dampers at the tower head can reduce the top node displacement by more than 28% while installing dampers on the tower can reduce the top node acceleration by more than 66%. Through comparison and analysis, the optimal scheme is obtained., authors=ZHANG Chunrui, ZHANG Fa, authorsList=ZHANG Chunrui, ZHANG Fa, authorCompany=Shandong Electric Power Engineering Consulting

软件,采用线性自回归滤波器法模拟随机脉动风荷载的时程样本;应用能量法计算所需阻尼器数量,根据阻尼器的工作原理和输电塔结构特点设计不同的阻尼器布置方案;对不同方案进行结构风致振动瞬态响应仿真,提取各方案控制点位移和加速度时间历程进行比较分析。模拟了多种风荷载,进一步对各方案的控制效果进行了对比分析。结果表明:SMA 阻尼器对输电塔风振控制效果较好;将阻尼器布置在塔头上,可有效控制塔顶位移,减振率在28%以上;在塔身上布置阻尼器,可有效控制塔顶加速度,减振率在66%以上。通过综合比较,选出了阻尼器的最佳布置方案。, authors=张春蕊, 张发, authorsList=张春蕊, 张发, authorCompany=山东电力工程咨询院有限公司, 济南 250013, correspAuthors=null,
