摘要
调谐质量阻尼器对结构的减振作用过程,本质上也是一个能量的传递、转化与耗散的过程。首先,根据能量法原理,对TMD-结构体系的能量平衡进行了较详细的分析,深入了解其在整个地震过程中各部分能量的分配组成和传递机理;然后,通过TMD-结构模型的模拟振动台试验研究,对TMD-结构体系的能量平衡进行了分析,从试验上进一步验证了TMD-结构体系的能量平衡理论,为下一步对TMD-结构体系的能量分析奠定试验基础。
The process of damping effect of structure due to tuned mass damper, in essence, is the process of transfer, conversion and dissipation of energy. Firstly, according to the the principle of the energy method, the energy balances of the TMD-structure system was analyzed in detail, and a deeply understand of the distribution, composition and the transfer mechanism of the energy of each part was made in the whole earthquake process; Then, based on shaking table test, the energy balance analysis of TMD-structure system was carried out, and the energy equilibrium theory of TMD-structure system was further verified experimentally, which established an experi- mental foundation for the next studying on the energy analysis of TMD-structure.
