滚动轴承性能不确定性与可靠性评估
Evaluation of Rolling Bearing Performance Uncertainty and Reliability
摘要
Abstract
Based on the grey system theory and Poisson counting process,the performance uncer-tainty of rolling bearings was quantified by a parameter,and the performance reliability of the bear-ings under different working conditions was analyzed via setting threshold value,then the perform-ance matching sequences of uncertainty and reliability were established to find out the internal connec-tion between the two items in bearing service processes.According to a property time series during the bearing operations,its uncertainty was obtained by grey bootstrap processing.Referencing the setting threshold to Poisson count,the time series effective variation strength was gained,then the perform-ance reliability was acquired.Finally,the grey relation between uncertainty and reliability was ana-lyzed.Experimental results show that the evolution information of rolling bearing performance uncer-tainty and reliability may be really described,the normalization processing results of the two are very sim-ilar and presenting obvious grey relation.The experimental results of various cases keep good consistency.关键词
