研究了单向和双向调谐液体阻尼器（TLD）在随机激励下的性能。调谐液体阻尼器的性能是衡量的效率和鲁棒性。对模型结构调谐液体阻尼器系统进行了一系列实验测试，以评估其性能，然后与众所周知的调谐质量阻尼器进行比较。有效阻尼计算进行的每个测试和效率和鲁棒性随后检查。实验研究了失谐阻尼器的性能，以突出这些被动动力吸振器的鲁棒性。采用非线性数值模型对调谐液体阻尼器的性能进行了广泛的参数研究。这项研究导致了调谐液体阻尼器的性能图表的发展。这些图表允许调谐液体阻尼器的效率被检查的一些变化的参数，其中包括激励振幅，水深，和建筑物的频率。当结构的精确频率未知时，这些图表对于调谐液体阻尼器的初始设计特别有用。
This paper investigates the performance of unidirectional and bidirectional tuned liquid dampers (TLDs) under random excitation. The performance of the tuned liquid dampers is measured in terms of efficiency and robustness. A series of experimental tests are conducted on model scale structure-tuned liquid damper systems to evaluate their performance, which is then compared to that of the well known tuned mass damper. The effective damping is calculated for each test conducted and the efficiency and robustness are subsequently examined. The performance of a mistuned TLD is experimentally investigated to highlight the robustness of these passive dynamic vibration absorbers. A nonlinear numerical model is used to conduct an extensive parametric study on the performance of a tuned liquid damper. This study has resulted in the development of performance charts for a tuned liquid damper. These charts allow the efficiency of a tuned liquid damper to be examined for a number of varying parameters, which include the excitation amplitude, water depth, and building frequency. These charts are particularly useful for the initial design of a tuned liquid damper when the precise frequency of the structure is not known.
