Chat OnlineVibration analysisFFT representation of the raw signal. The reason there is no big amplitude at 1x BPFO of the raw acceleration signal can be explained as follows. When a ball hits the crack in the outer race the actual vibration that occurs due to the hit has a much higher frequency than the BPFO.
Chat Online· Rolling mill vibration is no different. The most damaging modes of mill vibration involve some very specific natural resonances of the mill stand. If no structural resonances are excited then the vibration amplitude is simply a consequence of the way the mill responds to a cyclic exciting force acting at a particular location within the mill.

Chat OnlineThe vibration frequency for the hot rolling mill in general is 10-70 Hz. As a result the vibration increases with mill modulus control AGC gain for the large sensitivity frequency range of hot rolling mills. For these frequencies the mill modulus control gain can be decreased to relieve mill vibration. 5.
Chat Online· The vibration amplitude at the second set of conditions was measured at 8 microinches versus 79 microinches when grinding at first set of conditions. Again the imbalance remained the same. But grinding at conditions consistent with contact-length filtering produced a smooth surface despite the imbalance without any reduction in productivity.
