技術說明

一種防振腳座健康狀態監測裝置，其可包含複數個振動偵測器、訊號擷取器及訊號處理器。該些振動偵測器可偵測機械裝置之振動訊號；機械裝置可包含複數個防振腳座。訊號擷取器可擷取該些振動偵測器之振動訊號。訊號處理器可執行模態頻率分析程序以分析該些振動偵測器之振動訊號，並可計算該些防振腳座之目前狀態之自然頻率所對應之模態以做為測試模態，再將測試模態與該些防振腳座在最佳化狀態之自然頻率對應之參考模態比對以判斷該些防振腳座之健康狀態。 A device for monitoring the healthy status of a machinery mount is provided, which may include a plurality of vibration detectors, a signal acquisition device and a signal processor. The vibration detectors may detect the vibration signals from of a machine device, where the machine device may include a plurality of machinery mounts. The signal acquisition device may receive the vibration signals of the vibration detector. The signal processor may execute a modal frequency analysis process to analyze the vibration signals of the vibration detectors, and calculate a modal corresponding to the natural frequency of the machinery mounts in current status to serve as the test modal; then, the signal processor may compare the test modal with a reference modal to determine the healthy status of the machinery mounts, where the reference model is corresponding to the natural frequency of the machinery mounts in the optimized status.
