摘要

设计制作了一个具有动力等效的高耸结构缩比模型(TLCD减振模型),并采用位移张弛激励方式来模拟阵风载荷对高耸结构进行失稳加载,应用LMS Test.1ab振动噪声集成试验系统的动力测试平台,进行一系列测试试验,查看TLCD阻尼器的结构减振性能效果,并对TLCD阻尼器减振效果的主要影响因素进行了研究。结果表明,TLCD液体质量和液体有效长度对TLCD阻尼器减振效果有较大影响。
This paper designed a power equivalent to the high-rise structure of the scale model and TLCD damping model,and took displacement relaxation incentives to simulate the gust load in the high-rise structure,and applied the LMS Test.Lab vibration noise power of the integrated test system to conduct a series of tests and observed the TLCD vibration reduction effects and the main factors.The testing results showed that the quality and the length of the TLCD effective liquid have a greater impact.
