Abstract
Au cours d’un essai d’une turbomachine, le flottement de la soufflante peut être surveillé au moyen d’un algorithme prédictif préalablement entraîné, recevant en entrée des signaux dynamiques provenant respectivement d’au moins un capteur de vibrations agencé dans la turbomachine de manière à surveiller l’état d’un palier, et d’au moins un microphone équipant le banc d’essai, et un signal de régime provenant d’au moins un capteur de régime agencé dans la turbomachine, et donc sans recourir à des capteurs spécifiques. L’entraînement de l’algorithme prédictif peut être mis en œuvre en constituant, pour une turbomachine de référence, une base de données d’apprentissage à partir de tels signaux et d’au moins un signal de référence provenant d’au moins un capteur de référence agencé dans la turbomachine de référence de manière à mesurer une amplitude de déplacement tangentiel d’au moins une aube de la soufflante. Figure pour l’abrégé : Figure 1During a test of a turbomachine, the flutter of the fan can be monitored by means of a previously trained predictive algorithm, receiving as input dynamic signals coming respectively from at least one vibration sensor arranged in the turbomachine. manner of monitoring the state of a bearing, and of at least one microphone fitted to the test bench, and a speed signal coming from at least one speed sensor arranged in the turbomachine, and therefore without resorting to specific sensors. The training of the predictive algorithm can be implemented by constituting, for a reference turbomachine, a learning database from such signals and at least one reference signal coming from at least one sensor reference arranged in the reference turbomachine so as to measure an amplitude of tangential movement of at least one blade of the fan.
