摘要
The method of the invention comprises: - a step (E10) of obtaining a signal s that can be modeled by a product of a high frequency signal s1 and a low frequency signal s2, generated by the rotating mechanical power transmission device and acquired by a sensor; - a step (E20) of determining estimates of the signals s1 and s2, minimising a difference between all or part of the signal s and a product of these estimates; - a step (E30) of analysing the estimates of the signals s1 and s2 in order to detect the presence of a defect affecting the rotating power transmission mechanical device; and, if a defect is detected following the analysis step (E40), a step (E50) of locating said defect from at least one of the estimates of the signals s1 and s2.
