METHOD OF ANALYZING A VIBRATORY SIGNAL FROM A ROTATION OF AT LEAST ONE MOBILE 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 a driving 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 of operation of the rotary mechanism (3) as a function of time, the first measurement step being carried out by means of at least one vibration sensor (6), • at least a second measurement 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 around an axis of rotation Z, Such an analysis method makes it possible to determine at least one range of exploitability of the signal vibratory.
