| Abstract: | Based on the situation of some online monitoring and diagnosing system for turbomachinery, this paper uses frequency spectrum of analysis and band-pass filter to calculate the shaft's rotative velocity from the vibration signals collected on site. The calculation precision in high or low speed and verible speed process are higher than 95%. This paper gives the Batvos band-pass filter's algorithm. |
