Application of a multi-beam vibrometer on industrial components

Laser Doppler vibrometry is a well proven tool for the non-contact measurement of vibration. The scanning of several measurement points allows to visualize the deflection shape of the component, ideally a 3D-operating deflection shape, if a 3-D scanner is applied. Measuring the points sequentially, however, requires stationary behavior during the measurement time. This cannot be guaranteed for many real objects. Therefore, a multipoint laser Doppler vibrometer has been developed by Polytec and the University of Stuttgart with Bosch as industrial partner. A short description of the measurement system is given. Applications for the parallel measurement of the vibration of several points are shown for non-stationary vibrating Bosch components such as power-tools or valves.
