IEC Vibration Standard Electro-Dynamic Vibration Shaker
Working Principle of Vibration Shaker
The working principle of the electromagnetic vibration exciter is
similar to a loudspeaker whereby electrical conductor is moved by the action of electromagnetic force in the
magnetic field. The force to accelerate the moving part is generated by the balance between driving current and
magnetic flux. Therefore, by controlling the driving current, one can control the vibration
generator.
The maximum acceleration level of the electromagnetic vibration
exciter is determined by the maximum current and the loading. At low frequency, displacement of moving
part is restricted such that the acceleration will not reach high level. The resonance frequency of
the moving element is set higher than the upper limit of the frequency range.
The performance of vibration generator can be reflected by the
chart that displays the maximum acceleration under different frequencies. By using a log-log plot,
the restriction of displacement can be expressed by a straight line with slope of 6 dB/octave.
