RESONANCE The Silent Killer of Rotating Machinery
Another way to excite the natural frequencies is from the machines vibration. As the machine runs up to speed the vibration from the turning of the shaft will sweep through the frequencies of interest hopefully and thus excite the natural frequencies. This is called a run up test. Conversely, when the machine loses power and runs down to rest again the vibration from the machine will excite the
