13-26: Accurately Determining Drive Shaft Natural Frequencies

Mechanical drive equipment must be selected correctly and operate smoothly with no vibration. Drive shafts must be designed and manufactured with precision to prevent operation near a natural frequency. We have gotten more sophisticated in determining and controlling the natural frequency of drive shafts. As a user, you must be cautious of the supplier you choose for your drive system critical components. Not all manufacturers have a sufficient level of understanding; therefore, any supplier should provide you with the data to support the natural frequency values they publish.
