DO-160 Simulation Transport Vibration Laboratory Testing Equipment
Working Principle of Vibration Shaker
The working principle of vibration tester 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.
