[Vibration Analysis]

Visualisation of vibrations on a shaker.
Quantitative vibration measurement.


PCB Board

Vibration testing of a PCB board on a electrodynamic shaker. The visualisation with the StrobeCAM shows the motion of the electroni components and the board..

Model shape of a Wing

The mode shape of a wing (aircraft model) is measured with the Q400 -System on a electrodynamic shaker. The Q400 system measures the fullfield 3D deformation with high precision.

Resonance Frequency

The free vibration of a aluminium plate that is clamped at one side os measured with the fast RTSS system. The plateis accelerated by an impulse at the free end. The fast RTSS system achieves a measurement rate of 1500Hz and can therefore resolve motion frequencies of up to 500Hz.
The images show the 100mm long free end of the plate and the diagrams with the time course of displacement and its fourier transformation. The measured Eigen frequency is 99,3 Hz.

Tuning fork

The vibration of a tuning fork that is measured with the fast RTSS system. The tuning fork is marked with a line sticker to improve the RTSS measurement accuracy. The fast RTSS system achieves a measurement rate of 1500Hz and can therefore resolve motion frequencies of up to 500Hz.
The images show the upper part of the tuning fork, the measured displacement and the fourier transformation. Die eigen frequency is 439,48Hz and reflects the tone A (440Hz).
