【摘要】 本文通过对固体模型,势流体模型以及流构耦合模型的建立以及计算,研究了调谐液体阻尼器的减震机制。首先对固体模型和势流体模型进行了静态分析和频域分析。在基础分析完成后对两者有机结合的流构耦合模型进行了隐式动力学计算与分析。计算得到了顶部有水箱和无水箱的建筑物在特定的水平振动荷载作用下,顶部的位移时程变化情况。计算表明:按照建筑物自振频率设计的水箱可以有效减小建筑物顶部的位移。更多还原

【Abstract】 Based on the solid model potential fluid model and the flow structure coupling model creates and calculation,this paper focus on study the damping mechanism of the tuned liquid damper.First,the solid model and the potential fluid model of static analysis and frequency domain analysis are executed,after the basis of the analysis is complete,implicit dynamics calculations and analysis are executed on the flow structure coupling model.The schedule changes of the displacement at the top of building are caculated under the condition of with TLD and without TLD in a specific level of vibration loads.Calculations show that: the TLD design in accordance with building natural frequency can effectively reduce the displacement of the top of the building.更多还原
