一种基于电机径向力主动注入的电驱动系统滚动轴承故障在线无损诊断新方法

Single-point fault and distributed fault of rolling bearings are two types of faults that need to be diagnosed in time. Conventional diagnostic methods based on fault impact or energy characteristics exhibit limited sensitivity in detecting slight bearing faults. To address this, this study focuses on the time-varying radial stiffness of the bearing system, which is highly sensitive to defects, to...
