Aligning the current permanent magnet bearing failure mode and the analysis of the common sense of the problem is in a single and loose state, can not be usefully used to improve the reliability of the permanent magnet bearing, the level of reliability, according to the relevant bearing common sense, will be based on the common sense of the body The mold method is applied to the failure mode of the permanent magnet bearing and the analysis of the common sense of the impact. After establishing the failure mode of the system standard and the analysis of the general knowledge management system, the utility model can be used to complete the commonality of the failure mode and influence analysis in the development and production process of the permanent magnet bearing product. And use.
The permanent magnet bearing is a magnetic circuit layout in which the permanent magnet and the magnetic conductor are matched. The magnetized permanent magnet can supply magnetic energy, and the permanent magnet and the magnetizer together constitute the first part of the permanent magnet bearing magnetic system. Because of its mechanical wear and tear, Low energy consumption, low noise, long life, no need for smooth and oil-free pollution, permanent magnet bearings are widely used in various types of high-speed rotating machinery, such as space technology, transportation and medical equipment.
In the process of using the permanent magnet bearing, the failure of the permanent magnet bearing product may be caused by various influential factors in the permanent magnet bearing system, so that the reliability of the permanent magnet bearing product cannot be satisfied and affects the operation of the entire rotating mechanical system. Function. Therefore, all potential failure modes and their influencing factors in the permanent magnet bearing products must be fully analyzed, and the common sense of permanent magnet bearing products is arranged and correlated using the common sense method, which is reliable for improving permanent magnet bearings. Sexual supply is useful for prevention and improvement. The common sense approach is to try to pass the most appropriate common sense to the most appropriate person at the most appropriate time so that they can make the best resolution plan [1]. However, in the tradition In the common sense management method, because of the lack of a consistent common sense model and common sense storage method, it is impossible to effectively ensure the timeliness and accuracy of common sense retrieval. Therefore, the author proposes the failure mode of permanent magnet bearing based on the common sense modeling method of ontology. In the failure mode and effect auslysis (FMEA), the concept of ontology is used to integrate all kinds of scattered FMEA common sense. , Complete the processing of permanent bearing FMEA useful knowledge.
