Laboratory equipment
With the 3D scanning vibrometer PSV-400-3D from Polytec, the three-dimensional vibration behavior of components can be determined. The vibrometer consists of 3 laser heads with an integrated camera and an evaluation unit. The vibrometer is currently used to develop a method for the indirect determination of parameters of structure-borne sound sources from the sound power emitted by typical structure-borne sound sources installed on plate-shaped structures.
