Due to its powder metallurgy production process,permanent magnetic materials are currently unable to manufacture continuous magnetic rail.Existing magnetic rails mostly adopt a single-layer structure with magnets arranged in sequence.However,there is a large magnetic repulsive force between adjacent magnets,which is not conducive to the close arrangement of magnets and seriously threatens the stability and safety of the magnetic rail.The modular composite permanent magnetic rail adopts a composite structure of"two layers of permanent magnets+one layer of ferromagnetic plate".The module can be easily assembled and disassembled through the design of the male and female ends,and the uniform distribution of magnetic field strength along the axial direction above it is optimized,which brings benifits to the smooth operation of the maglev train.By analyzing the force acting on six typical positions of magnets on the composite permanent magnetic rail module,the observation reveals the mechanism and conditions of static friction balancing internal force to enhance the stability of the magnetic rail,and leads to an optimization plan for the application of modular composite permanent magnetic rail.
