Experimental modal analysis

The FE-simulation can predict the resonant frequencies of a complex assembly quite well. Regarding the damping, however, deviations of typically 30% can occur if the sources of damping are not sufficiently known. With the help of experimental modal analysis we can determine the damping exactly and adapt the FE-models to reality from the point of view of damping. Usually a single measurement is sufficient to obtain valid data for future developments. The measurements are offered in cooperation with our research partner, the Institute for Machine Tools at the University of Stuttgart.
