Damage detection of motor pieces |
摘要 |
Method in which an acceleration signal (10) is recorded, the signal is transformed into a frequency signal (11), a spectral coherence calculation (12) is carried out between the signal and the same signal broken down into predetermined frequency components, derived from the engine operation regime, the number of sequences for which there is a correlation peak is counted and it is determined if this number is greater than a preset threshold.
