English term or phrase: engine first order related disturbance
Bonjour,
Sorry pour le contexte assez long mais que je juge utile pour comprendre ma question :-)
Convert the engine speed in revolutions per minute (RPM), recorded during duplication of the disturbance into Hertz , revolutions per second (RPS), by dividing the RPM by 60 seconds.
Compare the dominant frequency in Hz, recorded during duplication of the disturbance with the engine speed just converted into Hz, to determine if they are related.
If the dominant frequency in Hz, recorded during duplication of the disturbance and the engine speed, converted into Hz, ARE related, then an engine FIRST ORDER related disturbance is present.
Merci d'avance !

perturbation induite par le moteur, détectée une fois par rotation


Explanation:
Order = The number of disturbances or shakes in one revolution of a rotating component.
First Order Vibration = A vibration or motion that is felt or heard once per revolution of a particular rotating component.
