| Abstract: | The feature of oil whirl stability in rotating machinery was seudied. A mechod for extracting freely decaying response from on-line vibration measurement of the machinery is presented,and it is suggsted that the logarithmic decrement obtained from the decaying response can be used as the feature parameter to monitor the margin and trend of the stability.A practical example shows that the method is effective. |
