Apparatus for determining damage on structural components and work machine comprising such an apparatus

An apparatus comprising:

• at least one structure-borne sound sensor configured to detect structure-borne sound signals of one or more structural components of a work machine;
• a self-learning system comprising:
• a detection device configured to detect one or more detected changes relevant to structure-borne sound, one or more of the detected changes being selected from a group consisting of a state change, an environmental change, and a combination thereof;
• an evaluation device configured to:
• evaluate one or more of the detected structure-borne sound signals;
• and
• determine a damage state of at least one of the structural components of the work machine on a basis of a comparison of the one or more of the evaluated structure-borne sound signals with one or more structure-borne sound signal reference patterns;
• and
• at least one of:
• a regression analysis module;
• or
• an AI-based estimation module;
• the self-learning system configured to estimate at least one of:
• with the regression analysis module, an influence of at least one of the detected changes on the structure-borne sound of the work machine with the regression analysis module;
• with the regression analysis module or the AI-based estimation module, a correlation between one or more changes in one or more of the structure-borne sound signals and actual damage to one or more of the structural components;
• or
• with the AI-based estimation module, one or more of the detected structure-borne sound signals and one or more of the detected changes;
• and
• an adapting device configured to adapt one or more adaptations on a basis of at least one of the detected changes, one or more of the adaptations selected from a group consisting of one of the structure-borne sound signal reference patterns, an evaluation criterion, and a combination thereof.
