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 ...

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 ...

Get PriceVibration 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.
Get Price07-02-2019 · Further, it has also been suggested that the higher frequencies and amplitudes of vibration would be more effective in inducing higher neuromuscular stimulation. 42 However, the results of this study do not indicate that simply delivering a combination of higher frequency and amplitude necessarily induces higher neuromuscular response.
Get PriceThe 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.
Get PriceDiese Rolle spielen der Frequenzbereich und die Amplitude. Zu den technischen Angaben bei einer Vibrationsplatte zählen der Frequenzbereich und die Amplitude. Dabei bezeichnet die Frequenz die Anzahl der Vibrationen in einer bestimmten Zeit. Mit unterschiedlichen Einstellungen lassen sich besondere Effekte erzielen. So kann man bei einer geringen Frequenz von fünf bis 15 Hertz ideal das ...
Get PriceThe 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 ...
