本文探討拘束阻尼層(Constrained Layer Damping, CLD)運用於平板減振之最佳化分析，首先推導出部份覆蓋CLD平板之運動方程式，以構成本研究之理論基礎。續探討具部份覆蓋CLD平板結構，其覆蓋CLD面積大小、黏彈層厚度、拘束層厚度等物理參數改變時，對具部份覆蓋CLD平板結構固有頻率、阻尼及功率頻譜等之影響。
經由此三層板之參數效應分析後，依據最佳化設計觀念，定義出由功率頻譜、固有頻率偏移率與成本因子等性能指標所組合的目標函數，尋求最佳之減振設計，如覆蓋CLD之最佳貼覆面積與厚度。接續探討目標函數中各因子權重變化對於功率頻譜、固有頻率偏移率與成本因子的影響。文末並進行簡單之實驗，藉以了解實驗之基本架設與原理。

This thesis presents the studies on optimization and vibration reduction analysis for the constrained layer damping (CLD) treatment on a plate. At first, the equations of motion of the plate with CLD are derived which were the foundation of the research. We analyze when the change of the area , viscoelastic material’s thickness, and constrained layer’s thickness of partial CLD, the influence of natural frequency, damping factor, and power spectrum.
After the analysis on the effect of the three-layer’s parameter, we define the subject function which composed of power spectrum, the rate of nature frequencies’ deviation, and cost factor from the design of optimization. The parameters of the design include the area and thickness of the CLD. We discuss the influence on the power spectrum, natural frequencies’ deviation, and cost factor through the changing of the weighting factor of the subject function. Finally, we performed a simple experiment to realize the basic principle and how to set up about vibration experiment.
