摘要
为了分析滚动轴承振动的非线性特征与性能保持可靠性之间的关系,以混沌理论为基础,提出关联维数保持性的新概念,用其刻画滚动轴承振动的非线性特征;同时,基于最大熵原理和泊松计数原理,建立振动性能保持可靠性模型,进而建立滚动轴承振动的非线性特征与振动性能保持可靠性匹配序列。实验结果表明,滚动轴承振动的非线性特征与振动性能保持可靠性关系密切,它们的变化趋势具有一致性,可以根据关联维数保持性的变化趋势来推断振动性能保持可靠性的变化趋势。所提方法为滚动轴承的可靠性预测提供了一个新的思路。
In order to analyze the relationship between the nonlinear characteristics and the performance continuity reliability of rolling bearing vibration,based on chaos theory,a new concept is proposed for continuity relation dimension to characterize the nonlinear characteristics of rolling bearing vibration.Simultaneously,based on the maximum entropy principle and Poisson counting principle,the vibration performance continuity reliability model of the rolling bearing is established,and then the matching sequence of nonlinear characteris tics and the vibration performance continuity reliability of the rolling bearing vibration are established.The ex perimental results show that the evolution of nonlinear characteristics and the vibration performance continuity reliability of rolling bearing vibration are closely related to each other,and the trend of change is consistent and reliability changes can be inferred based on the changing trend of the relation dimension.The proposed method provides a novel idea for the reliability prediction of rolling bearings.
