摘　　要：为了分析滚动轴承的振动性能退化过程与保持可靠性之间的关系,提出一种基于最大熵法和相似度法的滚动轴承振动性能退化模型,并对滚动轴承的退化过程进行评估;然后基于最大熵法和泊松过程建立滚动轴承振动性能保持可靠性模型;最后基于灰关系理论对滚动轴承的性能退化序列和保持可靠性序列进行分析。实验结果表明,所提出的滚动轴承振动性能退化模型能够有效地识别滚动轴承的退化状态,并且滚动轴承振动性能保持可靠性的演变历程与振动性能退化过程之间有明显的灰关系,可信水平均达到80%以上。To investigate the relationship between the degradation process and the continuity reliability of rolling bearing vibration performance,the degradation model of rolling bearing vibration performance is proposed based on maximum entropy method and similarity method;then the continuity reliability model of rolling bearing vibration performance is established based on the maximum entropy method and poisson process;Finally,the Gray relation analysis is performed on the performance degradation sequence and the continuity reliability sequence of the rolling bearing. The experimental results show that the proposed degradation model of rolling bearing vibration performance can effectively identify the degenerative state of rolling bearings,and there is a clear gray relationship between the evolution processes of the continuity reliability and the degradation process of rolling bearing vibration performance,the credibility level exceeds 80%.
