    摘要:

    滚动轴承是一种最常用的机械设备,其性能退化评估是实现CBM(视情维修)的基础。但要找到一种具有可靠性好、效率高和故障预警早的滚动轴承监测系统是一个重大的挑战。提出了一种简单新颖的轴承性能退化评估时域方法,并将其运用于在滚动轴承故障模拟试验和全寿命测试实验,两种实验结果都表明:所提出方法能够清晰地描述故障程度变化趋势并能检测早期故障。

    Abstract:

    Rolling bearings are widely adopted for the mechanical equipment and the performance degradation assessment is the base to realize CBM (condition-based maintenance). Condition monitoring of rolling bearings has made certain progress over the past decades, but it is still a challenge to establish a monitoring system which has the advantages of high reliability, high efficiency and triggering an early warning of bearing faults. This paper presents a novel simple time-domain method for bearing performance degradation assessment, which was evaluated by simulated bearing fault signals and bearing run-to-failure test data. Both results demonstrate that the presented method is able to clearly describe the trend of bearing fault degree change and detect a fault at the early stage.
