APPLICATION OF A CONTINUOUS WAVELET TRANSFORMS AND ANFIS TO FAULT DIAGNOSIS OF A GEARBOX OF TRACTOR

摘要

This study proposes a technique based on continuous wavelet transform added by adaptive-neural-fuzzy?inference system (ANFIS) for fault diagnosis of gearbox of MF285 tractor. Varying fault can cause changes in a?measured gearbox vibration signal. A gear motion vibration signal in speed of 1500 r/min is analyzed as source data.?Energy of coefficients wavelet is proposed to evaluate tractor gear fault by ANFIS. We found that this technique can?correctly indicate early gear fault.
