Fuzzy analysis of bearing accelerated degradation testing with uncertainty

摘要：

　　This paper proposes a novel method of fuzzy analysis for bearing accelerated degradation testing, which extracts degradation index from bearing vibration signals under different accelerated levels and obtains fuzzy failure time based on fuzzy regression model in consideration of uncertainties.Identification of accelerated model is conducted through linear mixture model.The proposed method provides a methodology to do accelerated vibration analysis for rotating machinery products.An industrial application is used to verify its effectiveness.
