摘要：

摘要：为了跟踪滚动轴承故障发展过程，定期采集滚动轴承的振动信号，对不同频率范围的信号进行处理，得到振动尖峰能量谱和速度谱。通过对不同时间里的振动尖峰能量谱图和速度谱图的分析，获得轴承的当前状态，借此评估轴承的剩余寿命，为预知性维修提供科学的数据依据。

Abstract:

Abstract:In order to track the fault development process of the rolling bearing, the vibration signal data of the rolling bearing were collected periodically. The signals in different frequency range were processed to obtain gSE spectrum and velocity spectrum. Based on analysis of the gSE spectrum and velocity spectrum obtained in different time, the current status of the bearing was obtained, and the residual lifetime of the bearing can be estimated, which provides scientific data basis for predictive maintenance.
