要約(日本語): We proposed the recursive interpolated D/FFT (R-IpD/FFT) for overcoming short- and long- range leakage and achieving the on-line calculation. From the viewpoint of introducing condition based maintenance (CBM) into turbine and generator, we applied R-IpD/FFT to abnormal vibration generated on the turbine model with a rotor as shown in Fig.1 and evaluated it. R-IpD/FFT estimated the frequency components of displacement signal more accurately than R-DFT.
