Background

The railway development plan of the State iron road administration determines that: the speed per hour is pushed to 400 km grade to tell the railway shutdown technology, 600 km grade to tell the magnetic suspension system technology reserve and other important and important technologies. The construction of the railway network is completely told by the 'eight vertical and eight horizontal'; in practical applications, conventional railroad trains rely on various types of locomotives such as steam, fuel, electricity, etc. as traction power, and the interaction between wheels and rails is used as a running guide, and the railway lines are subjected to pressure to roll along the rails by means of the wheels. The maglev train is the most novel fifth generation transportation tool which depends on the characteristic that the like poles repel and the opposite poles attract of an electromagnetic field to support the train, so that the whole train is suspended on a line, is guided by the electromagnetic force, and directly converts electric energy into propelling force by a linear motor to push the train to advance. The magnetic suspension train is a novel transportation tool consisting of a non-contact magnetic support, a magnetic guide system and a linear driving system, and mainly comprises a superconducting electric magnetic suspension train, a normally conductive electromagnetic suction type high-speed magnetic suspension train and a normally conductive electromagnetic suction type medium-low speed magnetic suspension; the main force-generating component of the electric magnetic track brake is a brake electromagnet; the electromagnet is composed of an electromagnetic coil extending along the track direction and a magnetic core forming a base body or a supporting body similar to a horseshoe; the direct current flowing in the electromagnetic coil causes an excitation voltage which generates a magnetic flux in the core, which flux is short-circuited via the rail head once the braking electromagnet is placed on the rail; thereby generating a magnetic attraction force between the brake magnet and the rail; attracting the magnetic track brake along the rail by means of the kinetic energy of the moving rail vehicle through the transmission element; here, the braking force is formed by combining the sliding friction between the braking electromagnet and the rail with the magnetic attraction force; the magnitude of the braking force of the magnetic track brake is mainly determined by the magnetic resistance of the magnetic circuit, namely the geometric dimension and the magnetic permeability, the magnetic potential, the friction coefficient between the brake electromagnet and the rail condition; in principle, two different types of magnets can be distinguished by their structure; in a first embodiment, the braking electromagnet is a rigid magnet, to which two wear strips are screwed, which are separated longitudinally by a non-magnetic strip; the non-magnetic strip is used for avoiding magnetic short circuit inside the brake electromagnet; the rigid magnet is mostly used in urban trams and urban railways in short-distance traffic; the above situation requires a large number of magnet wires; how to rapidly produce the electromagnetic wires and simultaneously need the electromagnetic wires with stable performance is a difficult problem for researchers.
