How is Machine Vibration Described? - .

Vibration amplitude is thus an indication of the severity of vibration. In general, the severity or amplitude of vibration relates to: (a) the size of the vibratory movement (b) the speed of the movement (c) the force associated with the movement. In most situations it is the speed or velocity amplitude of a machine that gives the most useful information about the condition of the machine ...

Optimale Frequenzen bei Vibrationsplatten

Die Intensität hängt von Frequenz und Amplitude ab. Generell weisen seitenalternierender Vibrationsplatten eine deutlich höhere Amplitude auf, was dazu führt, dass bereits bei niedrigen Frequenzen genügend Intensität aufgebaut wird. Es gibt zwei Aspekte, die zu beachten sind: Die positive und fördernde Wirkung und das Risiko. Aus der Analyse des Risikos wissen wir, dass Vibration ...

01-09-1979 · The table vibration must be calibrated to help ensure conformance with a standard test method. A method for this calibration is given and the required apparatus is described. The results of a sample calibration of an electromagnetic vibrating table are shown both for the maximum amplitude setting of the vibrator power control and for various percentages of maximum power.

Oversæt denne side

Vibration monitoring instruments for pumps are generally characterised as velocimetric type. Velocimetric type instruments have a measuring range typically in inches/sec or mm/sec. Accelerometric (in inches/sec2 or mm/sec2) or distance-type (typically in microns) vibration readings are usually taken at bearings and shafts of more high-tech equipments like turbines.

The vibration amplitude is measured with a reference accelerometer (PCB Piezotronics model 352C23) and the offset shift is measured while the vibration amplitude is increased beyond the full-scale range. The truncated-mean models (fit to 2.5 g truncation) show a good fit to the measurements.

The bearing vibration is often not detectable due to the presence of process noise. To extract this signal, amplitude demodulation techniques have been developed. This term is synominous with envelope analysis, as the envelope of a signal is the amplitude of the carrier frequency. There are a variety of algorithms to perform this task, with the ...

A vibration machine with the correctly tuned amplitude and frequency setting will create a G-force that is significant enough for your body to respond and work, in terms of contracting and relaxing. If you were to use a machine with a super low 0.5 mm amplitude and 100 Hz frequency, you're not really going to achieve much because 1. your body physically simply cannot contract / relax 100 ...
