Abstract
An apparatus for detecting damage to a machine that is excited at a previously known frequency by a vibration exciter, including an acceleration sensor for recording a current amplitude spectrum of an upper mass. A previously known amplitude spectrum of the upper mass is stored in a memory device. The current amplitude spectrum is compared with the previously known amplitude spectrum in a comparison device. If the comparison device determines that the spectra differ from one another, a corresponding deviation signal is generated and is output via a display device for informing the operator in order to inform the latter of possible damage.
