| 摘 要： | 基于结构动力学和流体力学原理,对液体质量双调谐阻尼器(TLMD)的减振机理和计算公式作了推导,归纳了TLMD的设计方法。在此基础上,结合调谐质量阻尼器(TMD)的有限元模型,以及单自由度体系在给定初位移的自由振动试验,检验了TLMD设计方法的可行性与准确性。试验结果表明TLMD减振效果的试验值与模拟值吻合较好,且近似为调谐液体阻尼器(TLD)和TMD的叠加,整个设计过程较为简便。最后以30层钢框架结构的地震响应控制为例,演示了应用TLMD减震的设计过程。

| Abstract: | Based on the principle of dynamics of structures and fluid mechanics,the vibration reduction principle and the calculation formula of tuned liquid and mass damper (TLMD) were deduced,and the design method of TLMD was summarized.By combining the finite element model of TMD with the free vibration test of the single freedom system,the feasibility and accuracy of the TLMD design method were tested.Experimental results show that the damping effect of TLMD is in good agreement with the simulation results,and the vibration suppression effect of TLMD was approximate to the superposition effect of TLD and TMD.The design process is simple also.Eventually,taking a 30-story steel structure building for example,the design process of seismic damping by TLMD was demonstrated. |
