國立成功大學校鐘自1952年由聯勤總部兵工署鑄造完成，至今已為成大服務逾60載，為全台歷史最為悠久的校鐘之一，具有極大的文化與歷史價值。然而，由於鑄造年代久遠，相關製造技術資料遺失或不易保存，至今並無成大校鐘的材料、物理及機械性質等完整資訊與紀錄。故本文利用校鐘之原始放置空間整建為廣場，座落地點重新規劃且暫時存放於成大博物館期間，對校鐘之工程技術資訊進行全面性的研究與探討。
首先，對成大校鐘進行3D掃描建模、成分分析、振動與聲學量測以及頻譜分析，獲得相關之物理量與自然頻率。接著，藉助有限元素法，對掃描建構之模型進行模態分析，將求得之自然頻率數值解與實驗數據相互驗證與檢討。最後，以電腦輔助設計軟體SolidWorks對模型進行幾何參數與材料參數的修改與分析，並了解到鐘體的立體角、最大半徑、高度、厚度，乃至於音弓的高度與厚度都會對鐘聲音色產生程度不一的影響。而這些工程技術資料將大幅提升成大校鐘的文創價值，並可將之應用於各式鐘型樂器之設計。

The school bell of National Cheng-Kung University (NCKU) is one of the oldest bells among all universities in Taiwan and has a rich cultural value. Being casting at the end of 1952 by 60 Arsenal (at Kaohsiung) under the Combined Logistics Commands of Taiwan, this bell has serviced NCKU for many years. A comprehensive study of the bell from technical aspects thus has its special important meanings from cultural reservation. In this paper, the current progress on the technical aspect of this study is briefly reported, including 3D geometric modeling, vibration and acoustic experiments, material characterization and modal analysis using finite element method. It is expected that through this study, the engineering characteristics of the bell can be clarified and the obtained technical data would be helpful for revealing the related technology level of Taiwan six decades ago. We believe that in conjunction with its special historic role, these technical data would significantly enhance the culture value of the NCKU school bell.
