Concept and embedded tool for fault detection on mechanical structures

摘要

This paper presents a fault detection survey applied to the predictive maintenance and monitoring using the vibratory analysis of industrial mechanical systems. Based on manufacturers' considerations the Object-Oriented Concept "VIBRALYSE" is described here. It is illustrated by two applications involving an autonomous, low cost and versatile embedded device based on the spectral analysis. The first application concerns rotor spinning in textile industry. It involves the recognition of wear and tear of rotor bearings and the detection of a potential imbalance in the rotor. The second application is about a fault detection process applied to circular structures. This process is based on the model analysis and includes the development of an intelligent impactor.
