摘要
根据Fujino等提出的矩形TLD减振基本原理,建立了TLD中液体动水压力的控制方程,并采用有限差分法对矩形浅水TLD液体动水压力进行数值模拟。通过对某四层钢架多自由度结构体系在有TLD与无TLD的情况下分别进行模拟的计算结果比较可知,即使多自由度结构体系振型比较复杂,TLD对其仍具有比较好的减振作用,数值模拟结果与试验研究相符。
The governing equation of the water movement in the TLD based on the basic principle of the vibration suppression of the structure with shallow water TLD presented by Fujino, is derived. The finite difference method is used to simulate the dynamic liquid pressure. By comparing the results of the simulated response of the multi-degree of freedom structure with TLD and without TLD, it concludes that the TLD system can control the vibration of the structure effectively and the TLD system can be better used to the tall buildings.
