带调谐液体阻尼器结构的有限元模拟分析
|
摘要
调频液体阻尼器(TLD)作为一种被动耗能减震装置,由于涉及到两种形态的物质之间的相互作用,真实准确地掌握调谐液体阻尼器的减震特性显得尤为困难,因此建立更加精确的流固耦合模型,进而探讨带调谐液体阻尼器结构的抗震性能是一件非常有意义的工作。本文利用ADINA有限元分析软件分别建立了结构动力学模型和流体动力学模型,并利用其流-固耦合分析模块,对此耦合模型进行瞬态分析,模拟计算结果与试验简化模型的结果具有较好的一致性。在此基础上通过动力时程分析得到了调谐液体阻尼器流场的变化特性,并结合流场特性考查了频率比、地震动、质量比这三个因素对带调频液体阻尼器结构抗震性能的影响,对比分析表明频率比对TLD的减振性能的影响最为显著,最后给出了TLD的设计建议。
Tuned liquid damper is a passive energy dissipation device.It is very difficult to grasp the true and accurate characteristics of vibration reduction of tuned liquid damper,because of interaction between water and structure,thus it is becoming an important work to establish a more precise water-structure interaction mode,and discuss the seismic performance of the structure with tuned liquid damper.The fluid-structure interaction(FSI) mode of tuned liquid damper system is built with finite element analysis tool ADINA in this paper.Using the ADNIA FSI module,this fluid-structure interaction mode is calculated by Transient Analysis,simulation results is a good agreement with the test results of the simplified model.By Time history analysis,the instantaneous properties of the flow field of tuned liquid damper are obtained,and then based on this instantaneous properties of the flow field,the relationship between seismic performance of the structure with tuned liquid damper and three factors(frequency ratio,ground motion and mass ratio) is analyzed,the comparative analysis results show that frequency ratio is a most significant influencing factor.At last,some design advices of tuned liquid damper are given.
