13-26: Accurately Determining Drive Shaft Natural FrequenciesMechanical 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
