Development of fusion methods, modeling and classification of vibration indicators for monitoring mechanical assemblies based on the parameters of use. Application to the helicopter
The VHMS (Vibration Health Monitoring System) systems installed on helicopters have a role to increase in-flight safety for operators and passengers. These systems consist of recording in-flight operational data, particularly of a vibrational nature, and monitoring the integrity of mechanical assemblies through indicators derived from signal processing. The basic principle is based on the postulate that the appearance of a failure mode generates a characteristic change in the values of the indicators. A limitation encountered by VHMS systems is however linked to the strong dependence of the indicators on the flight conditions which, for the helicopters, are likely to vary rapidly and in complex ways. These variations, difficult to understand today, can mask the signs of mechanical failure.
