隨著科技進步,機械設備朝著大型化、自動化的方向發展,建築物的承載力、耐震程度等,乃是現今重要課題之一。大部分的機械設備,都可能產生機械震動及噪音,常使工作者感到不舒適,機械震動較嚴重者,可能造成機械設備喪失、降低原有的工作效能或損壞,乃至於建築物遭受破壞。 本研究之案例大樓約為民國80年代之建築,建築中精密機械設備眾多,震動測量實驗運用加速度規、NI動態訊號擷取模組、Labview圖形化程式編譯平台,利用Labview之便利性,進行震動訊號之測量、擷取、紀錄、分析與呈現,獲得之振幅及頻率依據現有之評估準則尺度進行分析、比對,即可得知震動對人、機械、建築物造成之影響有初步的瞭解,藉以提出震動可能造成之危害程度、改善措施,期於工程、科技業界提供機械震動影響評估指標性範例。
With the scientific and technological progress, machinery and equipment towards large-scale, the direction of automation, building capacity, the degree of earthquake, is one of the important issues today. Most of the machinery and equipment, may produce mechanical vibration and noise, often make the workers feel uncomfortable, more serious mechanical shock, may cause mechanical equipment loss, reduce the original work efficiency or damage, and even the building suffered damage. The case building of this study is about 80 years of construction, the construction of many precision machinery and equipment, vibration measurement experiments using the accelerometer, NI dynamic signal capture module, Labview graphical programming platform, the use of Labview convenience, Signal measurement, capture, record, analysis and presentation, the amplitude and frequency obtained according to the existing assessment criteria for the scale of analysis, comparison, you can know the vibration of people, machinery, buildings have a preliminary understanding of the impact, To promote the shock may cause harm, improve the measures, in the engineering, science and technology industry to provide mechanical shock impact assessment indicators of the example.
