Abstract:
The present invention relates to a method (100) for monitoring the health state of a mechanical apparatus or a mechanical component. The method comprises at least the following steps: i) acquiring actual vibration data collected in or on a mechanical apparatus or a mechanical component; and ii) on the basis of a health diagnosis model, determining, from the actual vibration data, whether an anomaly is present in the mechanical apparatus or the mechanical component, and the type and/or grade of the anomaly, wherein the health diagnosis model is constructed on the basis of calculated vibration data calculated by means of a big data corrected kinetic model of the mechanical apparatus or the mechanical component. The present invention further relates to an apparatus for monitoring the health state of a mechanical apparatus or a mechanical component, and a corresponding computer program product and a corresponding vehicle. According to the present invention, real-time and reliable health state monitoring of an electric motor and a gear drive apparatus are realized.
