环形调频液体阻尼器（TLD）的计算模型

MODELLING OF LIQUID SLOSHING IN THE ANNULAR REGION FOR DAMPER APPLICATION

本文建立了液体在刚性环形容器内晃动的计算模型，这一模型可以用于调频液体阻尼器（ＴＬＤ）及结构─ＴＬＤ相互作用的研究。为了验证计算模型，进行了一系列的振动台试验，研究液体晃动第一振型的频率和动力反应。用模型计算的结果与试验结果符合良好，计算模型基本合理。

For the study of damper application and structure-tuned liquid damper(TLD) interaction. a new mathematical model of liquid sloshing in an annular tank is presented. Forced vibration responses as well as free sloshing characteristics are elaborately examined by both shaking table experiments and theoretical analysis. Reasonable agreement is found between experimental results and theoretical analysis. Therefore the validity of the model is confirmed.
