未來研究方向

本文以臺灣核能電廠單盤體機櫃進行振動台試驗，並為進行單盤體機 櫃模型分析，但核能電廠機櫃大多為多盤體機櫃，於未來可朝多盤體電氣 盤體進行分析並探討。

由實驗可以發現，內含抽屜型式之機櫃其動態反應較不規律性，其因 為抽屜右上部跟左下部為由卡榫跟機櫃本身作結合，但每個卡榫間之細縫 大小不一，導致抽屜於受震時，其反應較不規律，故內含抽屜之機櫃於進 行實驗時，建議卡準部分須完全固定住，以降低含抽屜機櫃反應的不確定 性。實驗後，須再進行一次白噪音試驗，了解機櫃受震後之基本結構頻率 是否與實驗前差異甚多。

由於 MCC 電氣盤體部分構件為螺栓連接，自然頻率易隨輸入波強度及不 同輸入波而有所變化。本數值模型構件材料特性採用線彈性部分，較難準 確模擬出上述電氣盤體動力反應特性，於未來研究方面，建議可採用具非 線性數值模擬進行分析，以提升盤內反應譜模擬結果之準確性。而本數值 模擬機櫃之內含抽屜型式，未能模擬出抽屜型式之動態反應，故未來研究 方面仍可朝這方面進行探討。
