The Vibration Analyst Checklist – Do You Pass? | RMS Ltd · We have a high peak at 100 Hz (the line frequency was 50 Hz) and there are polepassfrequency sidebands. It is essential that the Fmax is set high enough to see all of the frequencies of interest (and harmonics of those frequencies), but it is also essential that you have sufficient resolution to correctly distinguish between those frequencies.
Understanding of resonance essential for solving vibration ... · Rotor critical speed: A rotor critical speed exists when a machine's rotating element is the resonant component and its speed matches the natural frequency of the rotor. This is common with centrifugal pumps, gas and steam turbines, and large, twopole electric motors. While the result is similar to structural resonance (high vibration at a certain operating speed), a rotor critical speed is ...

ResonanceResonance General. Resonance is simply the natural frequency of a component or combination of components (assembly). All structures have a resonant frequency. If you impact the structure with enough force to make it move, it will vibrate briefly at its natural frequency. A structure will have a resonant frequency in each of its 3 directional ...
Maximizing Screening EfficiencyOperations at Critical Frequencies • This screen suffered multiple cross member failures over a 3year period with very low loading conditions • Multiple screens recorded operation at or near critical frequencies requiring changes to speed and counterweight settings to prevent failures • Screens often require such adjustments for best longterm reliability Critical frequency 'peak ...
Techniques for Detailed Screening of Vibration Data ... · Certain vibration frequencies (relative to the machine rotating speed) relate to specific groups of machine faults—for example, rotor mass imbalance will cause 1x rpm vibration in the radial directions. For that reason, it makes sense to allow the software to scan the data collected for a group of machines and trigger an alarm if the 1x rpm vibration exceeds expected levels. Shaft
