Changes in case vibration readings are used to monitor rotating machinery condition. Absolute levels of vibration are indications of condition except where structural resonances (e.g.: bearing housings, or motor bases) amplify vibrations at certain frequencies (usually integer multiples of shaft speed). Dynamic response at vibration test points can be measured on new installations to assist in establishing standards for absolute vibrations. Also, changes in dynamic response over time can add to understanding of machine condition. Discussion of case history to illustrate points is included. Code: *************************************** |
