摘 要: Accurate Remaining Useful Life (RUL) prediction of critical assets is an important challenge in condition based maintenance to improve reliability and to decrease machine's breakdown and maintenance's cost. Bearing is one of the most important components in industries that need to be monitored and the user should predict its RUL. The challenge of this study is to propose a new strategy for RUL feature extraction. The proposed methodology provides better features in term of monotonicity. This specification ensures a better RUL prediction by comparing the test degradation features to the library of instance. Experimental results show that the proposed methodology is very promising for RUL estimation by industry.

对关键资产进行准确的剩余使用寿命(RUL)预测,是基于状态的维护中的一项重要挑战,旨在提高可靠性并降低设备故障和维护成本。轴承是工业领域中最关键的部件之一,需要持续监控,用户应对其寿命进行预测。本研究的挑战在于提出一种新的RUL特征提取策略。所提出的方案在单调性方面提供了更优的特征。该特性通过将测试退化特征与实例库进行比较,确保了更准确的RUL预测。实验结果表明,该方法在工业应用中的RUL估计方面具有很高的潜力。
