摘要

在現有文獻中，研究人員通常使用多個調諧質量阻尼器(MTMD)來抑制樑型式結構承受外部動態負載時，所引起的振動反應。對於板型式的結構而言，其文獻則相當有限。因此，本文的主要目的在於研究如何利用MTMD來對承受外部簡諧負載之板結構進行減振。一些和研究主題相關的參數，例如：MTMD的頻率範圍、頻率間格、阻尼比、質量比與總個數等，亦在本文中加以探討。由數值分析結果發現，上述參數對避振器的減振效率有相當大的影響。

In the existing literature, the researchers usually used MTMD (Multiple Tuned Mass Dampers) to suppress the vibration responses of beam-typed structures subjected to external dynamic loads. For the cases of plate-typed structures, the literature is limited. Thus, this paper studies the vibration reduction of a multi-degree-of-freedom plate-typed structure due to an external harmonic load using MTMD. Some important parameters closely relating to the current research topic, such as frequency range, frequency spacing, damping ratio, mass ratio and total number of MTMD, are investigated. From the presented numerical results, it is found that the above-mentioned parameters influence the vibration reduction effectiveness of MTMD significantly.
