Testo completoRunning turbomachines experience vibrations which reduce their operational lifetime. This is why vibratory monitoring is so important. Among the possible sensors, optical probes are cheap and easy to install. Moreover, they provide a signal whose sampling depends on their relative positions. So we have to deal with undersampled signals, or occasionnaly irregular sampling, without any conception information. A literature survey has allowed us to examine methods that present severe limitations : the need of conception information, excessive simplification of the model, or difficult interpretation of the results because of frequency uncertainties. Futhermore, we showed the advantage of regular over irregular probe disposition. Then we developed new methods, and distinguished the signals by their contents : one single or several frequency components. The methods of monocomponent signal processing rely on properties of graphical representations. In the case of multicomponents signals, we showed that, for the sake of saving probes, it is better to try to tolerate several ambiguities rather than to try to eliminate them. Then we proposed two kinds of instrumentation. One complementary to the other, they can be profitably exploited simultaneously. The first one, called "multirate", uses different groups made of different numbers of probes. This is equivalent to sampling the vibratory signal at several rates. The following analysis consists in a comparison of the resulting spectra. The second one, called "duos", exploits different groups made of the same number of probes, but shifted around the casing. The corresponding analysis utilises the relative phase of the apparent signal components. We tested those methods with signals wich are representative of real phenomena

Testo completoThe industrial and transportation sectors require more and more efficient and complex machines and installations increasing the risk of failure and disruption. This can lead to the immediate shutdown of a machine and disrupts the proper functioning of the entire production system. The diagnosis of industrial machines is essentially based on the monitoring of symptoms related to different degradation conditions. These symptoms can be derived from various sources of information, including vibration and acoustic signals. Nowadays, many effective techniques are well established, based on powerful tools offered by the theory of cyclostationary processes. The complexity of these tools requires an expert to use them and to interpret the results based on his/her experience. The continuous presence of the expert is expensive and difficult to achieve in practice. Condition indicators for rotating machines exist in the literature but they are conceived under the assumption of perfect operating conditions. They are limited, dispersed and generally not supported by theoretical frameworks. The main objective of this thesis is to reduce the use of human intervention by proposing strategies to design two optimal indicators that summarize diagnostic information into a scalar value. A distinction is made between two families in diagnosis: the case where prior information on the faults is known and the case where it is unknown. These indicators are designed to be used in an autonomous process without requiring human intervention, using statistical hypothesis tests. The capacity of these indicators is validated on real data and compared with other indicators from the literature in terms of detection performance
