摘　　要：对规则波作用下圆形调谐液体阻尼器的可行性及有效性进行了试验研究,探索调谐液体阻尼器对于固定式海洋平台结构减振的实用性。调谐液体阻尼器的减振性能通过结构响应的减小程度来评价。试验观测了容器中液体的运动形态,同时考虑容器的大小、数目,阻尼器与平台结构、波浪三者之间的频率比,质量比以及激振波浪参数等诸多因素的影响,得到了利用调谐液体阻尼器进行固定式海洋平台减振设计的具有指导意义的结论。The major objective of this study is to experimentally study the feasibility and effectiveness of circular Tuned Liquid Damper (TLD) for suppressing the dynamic response of the platform structure subjected to regular wave loading. The effectiveness of TLDs is evaluated based on their response reduction. By observing the behavior of the water in TLDs, the study investigates the effect of a number of parameters, including the container size, number of dampers, frequency ratio, mass ratio, and incident wave characteristics. Useful conclusions have been obtained for further fixed platform design.
