要約(日本語): We compared the abnormality with normal by using the fast independent component analysis. We measured with accelerometer at two positions and analyzed the signals associated with oil whip, which is one of abnormality. The sensors of each position are in vertical and horizontal directions. We separated these signals by using fast ICA.When oil whip was caused, the spectrum at 27Hz component appeared. The characteristic frequency appears in 60s after oil whip occurred.
