Vibration

To measure the acceleration or deceleration / the change in velocity of a body. (m/s²)

UUT is placed in a device then the device accelerates to a known Acceleration (m/s²) Often this is tested by measuring the DC output of an accelerometer on a centrifuge.

UUT is placed in a device, normally a shaker, which then moves in a single axis direction at a known acceleration at the reference frequency. Then the amplitude is changed and the difference in sensitivity is expressed as the slope of the best fit straight line between the data plotted as output (Voltage, IEPE, Current or Charge) vs Test amplitude. Ratio output of linearity expressed as the worst-case voltage difference between the measured value and the best fit straight line divided by the full-scale output (Voltage, IEPE, Current or Charge)*100 (expressed as a percentage).

UUT is placed in a device, normally a shaker, then the shaker moves in a single access direction at a known acceleration and frequency.

UUT is placed in a device, normally a shaker, which then moves in a single axis direction at a known acceleration at the set frequency. Then the amplitude is changed and the difference in sensitivity is expressed as the slope of the best fit straight line between the data plotted as output (Voltage, IEPE, Current or Charge) vs Test amplitude. Ratio output of linearity expressed as the worst case voltage difference between the measured value and the best fit straight line divided by the full scale output (Voltage, IEPE, Current or Charge)*100 (expressed as a percentage).
