Abstract

The invention belongs to the technical field of nuclear power, and particularly relates to an equipment remaining service life estimation method and device. The equipment vibration signal is analyzed to obtain the equipment health index. The vibration signal contains abundant health state information of the mechanical equipment, the health index is constructed by quantizing the vibration signal to represent the health state degradation trend of the equipment, and the degradation process of the equipment is modeled by adopting multiple degradation trends such as polynomial degradation based on the extracted health index of the equipment, so that the reliability of the equipment is improved. And finally, estimating the remaining usable life of the equipment based on the concept of a soft threshold. Therefore, real-time online monitoring, intelligent early warning, intelligent diagnosis and service life prediction of the system and the equipment are realized, the reliability analysis and management capability of the equipment is improved, and enterprise management personnel are helped to optimize maintenance decisions.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a method and a device for estimating the remaining service life of equipment. Background technique [0002] In the industrial field, due to the loss of equipment during use, the loss shows a phenomenon of continuous accumulation with different operating hours and operating conditions, which leads to a gradual reduction in the service life of the equipment. How to monitor the service life of equipment more objectively and accurately has become an urgent problem to be solved. Contents of the invention [0003] In order to overcome the problems existing in related technologies, a method and device for estimating the remaining service life of equipment are provided. [0004] According to an aspect of an embodiment of the present disclosure, there is provided a method for estimating the remaining service life of equipment, the method comprising: [0005] Collect ...
