在工業4.0的議題下，即時監測工具機為主要發展的目標之一，其中透過振動監測能夠對工具機的健康狀態做有效的分析，如顫震、軸承損壞等等。然而工具機會激發由低頻至高頻的振動頻率，而市面上任一的振動感測器無法兼具高頻寬、高靈敏度的特性以量測工具機的振動，同時以智慧製造為主要發展的目標之下，並且若要將振動感測器用於監測大量機台的振動狀態，還須具備有低成本的特性。因此在本文整合多個不同頻寬的低成本的微機電加速規，並使用機構設計將電路與多個微機電加速規整合，並且考慮加速規本身靈敏度低的缺陷，藉由電路設計提升加速規的靈敏度，而在訊號傳輸後使用數位濾波器做初步的資料統合，形成一個高頻寬、高靈敏度、低成本且三軸的整合多波段加速規模組，並將加速規模組初步在激振器上驗證靈敏度及頻寬，再應用於工具機主軸量測不平衡負載實驗及真實的切削情形，並討論其結果。除了量測工具機主軸的振動之外，本研究將加速規模組應用於智慧主軸鑽削平台，量測鑽削時的振動情形，以及機械手臂異音監測，量測機械手臂異常時的振動訊號，達到監測機台之效用。

In this thesis a design to form a vibrating sensing module by integrating several MEMS accelerometers with different dynamic characteristics is proposed and investigated. By such an approach, a low cost accelerometer with better dynamic behavior at any frequencies is expected. This work presents the preliminary study toward this goal. The primary test results on the dynamic performance characterization indicated that those MEMS accelerometers are potentially capable for measuring vibrations of machine tools. The in-situ on spindle also indicated that the performance of MEMS accelerometer could potentially compete with that of piezoelectric ones. Meanwhile, the Butterworth filter is efficient to eliminate redundant information. In the future, this vibration sensing module is expected to be used in monitoring a wide variety of machine tools and even more other realms.
