Abstract
An apparatus for determining damage on structural components, for example large rolling bearings, on work machines, in particular construction, material handling and/or conveying machines, including at least one structure-borne sound sensor for detecting structure-borne sound signals of at least one structural component of the work machine, and also an evaluation device for evaluating the detected structure-borne sound signals and determining the damage state on the basis of a comparison of the detected structure-borne sound signals with at least one structure-borne sound signal reference pattern, provision being made of a detection device for detecting state and/or environmental changes relevant to structure-borne sound, and also an adapting device for adapting the at least one structure-borne sound signal reference pattern and/or an evaluation criterion of the evaluation device on the basis of the detected state and/or environmental changes.
