A Maintenance Managers Guide to... Vibration Analysis and Associated Techniques in Condition Monitoring

摘要

Part 3: Using Monitoring Information and the practicalties of choosing and using vibration analysis and associated techniques in a CM programme. Whole machine or overall vibration occurring in the 10Hz-10KHz band is considered the best parameter for monitoring structural problems like imbalance, looseness, etc., and many such problems will cause excessive whole machine vibration. Measurements can either be trended to produce an ongoing evaluation of condition or the values obtained compared to the machine's 'normal' value (ISO 2372). The latter is commonly accepted as a one-shot indication of the machine's 'health'.
