| Abstract: | The basic theory of FFT analysis and the order analysis were introduced.The superiority of the order analysis was investigated in obtaining the characteristic value of rotating machinery.Based on LabVIEW,the way of programming was explained in detail to implement the order analysis;and the rotating speed signal was gained by interpolation in order to obtain the angle sampling vibration signal.The feasibility and accuracy of the order analysis were verified by experiments. |
