Embodiment Construction
[0065] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.
[0066] The technical problems to be solved by the present invention are: 1. Due to individual differences in bearings and differences in the types of failures that occur, it is difficult for the life prediction model trained by the traditional method to obtain a single degradation mode to achieve a good remaining life prediction effect under other degradation modes; 2. For the rolling bearing da...
