中文摘要 隨著科技產業的蓬勃發展,科技廠房的建造需求越來越多。然而,科技日新月異,生產的精密度也越來越高,隨之來的是科技產業對於工作環境的要求日趨嚴苛,尤其是廠房建築物的振動要求。產生振動的原因,除了地震之外,還包含了人員的走動、附近的交通影響、以及環境因素。更重要的還有生產設備本身產生的微振,引致廠房內部造成更大的振動,連帶影響其他生產機台。
有鑑於此,設備振動引致廠房微振的研究工作需進行更多的了解與研究,本研究分為兩部分,第一部分為在一精密機械廠房進行微振動量測實驗,取得現地的樓板振動資料,分別量測在工作時間,工具機台啟用時的樓板振動量,與夜間機台關閉時的背景振動值。其他包括微振動量測儀器的使用與架設、量測程式的操作與量測數據的分析。量測結果顯示,機台引致的振動在高頻較明顯,且在垂直方向有較大的振動;第二部分,將進行有線元素的分析,建立一廠房的模型,透過變更模型的細部結構尺寸進行分析,了解結構物的尺寸大小對微振動在樓板上的傳遞與影響,結果顯示,在此結構物模型中,透過放大梁深,可以降低同樓層的振動大小;增加樓板厚可以降低低頻的振動。

英文摘要 With the development of the technology industry, the standard of production precision is getting strict, and the technology industry is increasingly demanding the working environment, especially the vibration requirements of buildings. Therefore, the standard for micro-vibration is significant for high-tech factory. The cause of the vibration also includes the movement of people, the influence of nearby vehicles and environmental factors. However, the most important is the micro-vibration induced by the production equipment inside the plant, which affects other production machines. In this situation, the research of micro-vibration induced by equipment is necessary.
There are two parts in this study. The first part is a micro-vibration measurement experiment hold in a precision machinery factory to obtain the vibration data of the floor in the field. We measured the vibration data of floor when the machine is working and the background vibration data when the machine is turn off in the night. The measurement results show that the vibration induced by the machine is obvious at high frequency and has large vibration in the vertical direction. The second part is performing an analysis of the finite element model. Building a model of a factory structure, and analyzing by changing the detailed structure size of the model, we can study on the influence of size of the structure on the vibration transmission on the floor. The analysis results show that in this structure model, the vibration of the same floor can be reduced after amplifying the beam depth; increasing the thickness of the floor can reduce the vibration of the low frequency.
