20.500.12556/RUL-134721 Early detection of defects in gear systems using autocorrelation of morlet wavelet transforms Zgodnje odkrivanje okvar na zobniških prenosnikih z Morletovo valčno transformacijo In recent days, supervision task of industrial systems is vital and the prediction of damages avoids many problems. If any system' defects are not detected in early stage, this system will continue in degradation and may be causing serious economic loss. In the industrial systems, the defects change the behavior and characteristics of the vibration signal. This change is the signature of the presence of the defect. The challenge is the early detection of this signature. The difficulty of the vibration signal is that the signal is very noisy, non-stationary and non-linear. In this study, a new method for early defect detection of a gear system is proposed. This approach is based on vibration analysis by trying to find defect's signature in the vibration signal. This approach has used the Autocorrelation of Morlet Wavelet Transforms (AMWT). Firstly, the simulation validation is introduced. The validation of the approach on real system is given in the second validation part. autocorrelation early fault diagnosis gear systems vibration analysis scalograms morlet wavelet transforms avtokorelacija Morletovih valčnih transformacij zgodnje diagnosticiranje napak zobniški prenosniki analiza vibracij skalogrami true false true Angleški jezik Slovenski jezik Članek v reviji 2022-01-27 14:16:38 2022-01-27 14:16:39 2022-09-14 04:09:32 0000-00-00 00:00:00 2022 0 0 Str. 56-65 no. 1 Vol. 68 Jan. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.8:517.44 0039-2480 10.5545/sv-jme.2021.7384 95304195 RAZ_Ayad_Mouloud_2022.pdf RAZ_Ayad_Mouloud_2022.pdf 1 6FEE73FE1F67B72E5112E7724686F77F e6ab3ae4137691e305cb7bb81e3ba62bc4063fca0e007efea65e9a3598fe2d17 7e7ccbc9-7f73-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153323 https://www.sv-jme.eu/sl/article/early-detection-of-defect-in-gear-systems-using-autocorrelation-of-morlet-wavelet-transforms/ 1 294b0035-7f73-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153322 Fakulteta za strojništvo Strojniški vestnik 0 0 0
