METHOD OF ANALYSIS OF A VIBRATORY SIGNAL RESULTING FROM A ROTATION OF AT LEAST ONE MOVABLE PART BELONGING TO A ROTATING MECHANISM

摘要

The present invention relates to a method for analyzing a vibratory signal resulting from a rotation of at least one moving part (2) belonging to a rotating mechanism (3) forming all or part of a kinematic transmission chain (4). ) of an engine torque, the rotating mechanism (3) equipping an aircraft (5, 5 '), the method comprising: • at least a first measurement step comprising a measurement of the vibrations in at least one direction and generating a vibratory signal operation of the rotating mechanism (3) as a function of time, the first measuring step being carried out by means of at least one vibratory sensor (6), • at least one second measuring step comprising a measurement of an angular position of the moving part (2), this moving part (2) comprising at least one degree of freedom in rotation respectively about an axis of rotation Z, Such an analysis method makes it possible to determine at least one operability range of the signal vibratory.
