Abstract

L'invention concerne un dispositif de surveillance de durée de vie d'au moins un équipement hydraulique d'un aéronef soumis à des variations de pression hydraulique (P) en vol, le dispositif comportant une interface de réception de données de mesure représentatives de la pression hydraulique (P) de l'équipement en fonction du temps (t) en vol, L'invention est caractérisée en ce que le dispositif comporte un dispositif de traitement, comportant un moyen pour détecter, à partir des données de mesure, une sollicitation (SOLLEND) en pression (P) à caractère endommageant, définie par le fait que la pression (P) comporte une augmentation (ΔPAUG) de pression, supérieure à un seuil déterminé (SΔP) d'endommagement supérieur à zéro, suivie d'une diminution (ΔPDIM) de pression supérieure au seuil déterminé (SΔP) d'endommagement, et un moyen de comptage pour compter le nombre (MEND) de sollicitations (SOLLEND) en pression (P) à caractère endommageant.The invention relates to a device for monitoring the life of at least one hydraulic equipment item of an aircraft subjected to variations in hydraulic pressure (P) in flight, the device comprising an interface for receiving measurement data representative of the hydraulic pressure (P) of the equipment as a function of time (t) in flight, The invention is characterized in that the device comprises a processing device, comprising a means for detecting, from the measurement data, a stress (SOLLEND) in pressure (P) of a damaging nature, defined by the fact that the pressure (P) includes an increase (ΔPAUG) in pressure, greater than a determined threshold (SΔP) of damage greater than zero, followed by a decrease (ΔPDIM) of pressure greater than the determined threshold (SΔP) of damage, and a counting means for counting the number (MEND) of stresses (SOLLEND) in pressure (P) of a damaging nature.
