Year: 2025

Type: article

Abstract: Efficient and high-precision magnetic grinding technology has become a bottleneck technology for the manufacturing and repair of high-performance aircraft engines. Previous studies have mostly focused solely on quality control to determine the effectiveness and feasibility conditions for optimizing the design of magnetic pole grinding devices. This method is far from meeting the needs of precise and efficient magnetic grinding of the inner surface of aircraft engine bent pipes. This article introduced the method and mechanism of precision magnetic grinding of the inner surface of aircraft engine bent pipes. This article proposed the optimization theory of permanent magnetic pole taper structure based on auxiliary slotted magnetic pole structure and the finite element model of magnetic pole taper of slotted auxiliary magnetic pole structure. This article summarized the influence of the taper of permanent magnetic poles based on auxiliary slotted magnetic poles on magnetic grinding and summarized the evaluation method for the optimization effect of magnetic grinding devices. This article listed the application of magnetic pole device optimization in precision magnetic grinding of the inner surface of aircraft engine bent pipes. This article provided an outlook on the development trend in precision magnetic grinding magnetic pole devices for the inner surface of aircraft engine bent pipes. The conclusion was drawn that establishing a three-dimensional discrete finite element model based on slotted magnetic poles can improve the accuracy and efficiency of magnetic research.
