摘 要: For Remaining useful life (RUL) prediction, this article presents a paradigm that separates the whole bearing life into many health states and then builds unique local regression models for each of those states, rather than searching for an overall regression model with multiple health state assessments. A method that utilised both unsupervised learnings and supervised learning to estimate a bearing's real-time health status is presented without previous information. The primary technology used to perform health status assessment and RUL prediction is the support vector machine. The efficacy of the suggested framework has been shown via experiments, including accelerated deterioration testing on rolling element bearings.

在剩余使用寿命(RUL)预测方面,本文提出了一种新的方法论:将轴承的整个寿命划分为多个健康状态,并针对每个状态分别构建独特的局部回归模型,而非通过综合多个健康状态评估来寻找整体回归模型。该方法无需预先信息,结合了无监督学习和监督学习,用于估计轴承的实时健康状态。主要采用的技术是支持向量机,用于健康状态评估和剩余使用寿命预测。该框架的有效性已通过实验验证,包括对滚动轴承的加速劣化测试。
