基于振动时间序列和威布尔估计的轴承性能动态分析
Dynamic Prediction of Bearing Performance Based on Vibration Time Series and Weibull Estimation
摘要
Abstract
Weibull estimation is often used to analyze the rated life and life dispersion degree of batch bearings,and Vibration time series of bearing in different operating states provide data foundation for statistics-theory-based Weibul distribution.Based on Weibull estimation,this paper analyzes the vibration time subseries in the stability interval of the test,and realizes the dynamic prediction of bearing faults through the change of Weibull parameter.The results show that the Weibull parameters of vibration subsequence change before vibration acceleration,which proves that the traditional Weibull estimation method can be applied to the analysis of single bearing state evolution.关键词
