第四章 盤內反應譜分析與動力放大因子

反應譜部分：
1. 試驗機櫃內部改變設備物重量，低頻區域之機櫃反應無顯著差異，但於 高頻部分質量櫃(mass)反應大於空櫃(bare)之反應。
2. 由不同量測點位之反應譜比較，X 及 Y 方向反應均隨量測高度增加而 反應提升，櫃內反應均大於櫃外反應，且發現當高度增加時，反應譜之 峰值所對應之頻率有變小趨勢，強震反應峰值所對應之頻率皆低於白噪 音試驗之頻率；Z 方向之反應，受到櫃內有無抽屜之影響，無抽屜型式 之反應無明顯變化，但含有抽屜組別反應於高頻部分有明顯放大反應，
表示抽屜受震時，有上下跳動反應。
3. 輸入波強度不同，其反應為隨強度增加而反應變大，並發現加速度反應 譜尖峰值所對應之頻率隨之減少，代表機櫃內部材料開始進入降伏階 段。
4. 不同型式之輸入波，X 方向均為 OBE 試驗波大於 IEEE693 試驗波，Y 向反應為 OBE 試驗波略小於或等於 IEEE693 試驗波，Z 方向為 OBE
104
試驗波反應均比 IEEE693 試驗波反應高。可發現 IEEE693 地震力主要 頻率落在低頻處(f<20Hz)，OBE 地震力主要頻率落在高頻處(f>20Hz)，
代表機櫃受到不同地震類型，其受震反應頻率皆不一樣。
放大因子之部分：
1. 當機櫃內有無設備物時，低頻範圍空櫃與質量櫃反應差異不大，高頻部 分為質量櫃反應大於空櫃反應，且高頻部分之尖峰值頻率較空櫃頻率 低，其原因為機櫃內部增加質量塊時，會導致面板模態頻率降低，但對 整體機櫃之頻率較無影響。
2. 不同點位量測位置比較，發現加速度放大因子反應與反應譜所顯示之趨 勢相似。
3. 地震強度之不同，可發現地震力增加其放大因子並無放大之現象。
4. 不同型式之地震波其放大因子反應，於低頻區 IEEE693 輸入波與 OBE 輸入波反應相似，但在高頻部分，X 及 Y 方向均為 OBE 輸入波反應均 大於IEEE693 輸入波，Z 方向則為 IEEE693 輸入波較 OBE 輸入波高。
由以上不同項目比較結果，影響盤內反應譜(ICRS)及放大因子(AF)主要 為設備物之高度，其次為輸入波大小，並可發現機櫃內部加速度反應均高 於機櫃外部之加速度反應，且OBE 試驗波對機櫃造成之主要頻率位於高頻 範圍，則 IEEE693 試驗波造成機櫃主要頻率範圍均在低頻部分。而動力放 大因子主要會隨高度提升，其放大倍率也會隨之變大，故要計算簡化之動 力放大因子，可由櫃內之最高處所得之加速度反應譜與底部反應譜相除所 得，本實驗之 AF 值主要落於 2~3 倍居多，接近文獻【6】中所建議之 AF 值 3.0。
