System And Methods For Analysing Vibroacoustic Measurements

Abstract: Method for training a model configured to analyse, for maintenance prediction, vibroacoustic measurements from an apparatus. The method comprises selecting at least one section in temporal vibroacoustic measurement data related to at least one individual mechanical event of the apparatus. The method further comprises labelling the at least one section based on order of occurrence or based on knowledge of the individual mechanical event. The method further comprises training the model using the at least one labelled section by comparing the at least one labelled section with a mechanical simulation. Existence of a temporal vibroacoustic measurement data that corresponds to at least one labelled section is then identified.
