在高层建筑的实际设计中,风振舒适度的控制是结构设计的一项重要内容。传统TMD结构间存在机械磨损,阻尼比调节范围小等缺陷,永磁式TMD可以避免这些缺点,经济技术上均优于传统TMD。根据电涡流阻尼器的原理,运用理论分析,提出合理的假设,建立电涡流阻尼器阻尼比与电磁之间的解析式,制作模型进行验证理论分析成果,总结永磁式阻尼器作用效果和应用前景。
In the actual design of tall buildings, the control of wind vibration comfort is an important part of the structural design. Traditional TMD structure has mechanical wear and damping ratio adjustment range of small defects, permanent magnet TMD can avoid these shortcomings, both economically and technically superior to the traditional TMD. According to the theory of eddy current damper, the reasonable assumptions are put forward based on theory analysis, the analytic formula between the damping ratio and electromagnetic of eddy current damper is established, and the theoretical analysis results of the model are established to summarize the effect and application of the permanent magnet damper prospect.
