Description
Technical Field
The invention relates to the technical field of rail vehicle braking, in particular to a linear vortex braking device for a high-speed train.
Background
The basic braking technology is one of key technologies of high-speed trains, and because of the huge braking energy of the high-speed trains, the safe stopping and deceleration control are difficult to realize within a specified braking distance. The high-speed trains in the world commonly adopt a composite braking mode with a plurality of braking modes matched, and the main braking modes comprise regenerative braking, resistance braking, friction braking, eddy current braking, magnetic track braking, aerodynamic braking and the like. The motor train unit in China adopts a mode of regenerative braking and friction braking (disc braking), and is the mode of most applied high-speed trains in the world at present. Both the two modes need to exert the braking effect through the adhesive force between the wheel rails, but under the severe weather conditions such as rain, snow and the like, the adhesive state of the wheel rails is poor, the exertion of braking force is influenced, and the braking distance is difficult to ensure; with the increase of the train speed, the wheel track adhesion coefficient is gradually reduced, so that the braking force of a high-speed section is insufficient, the braking distance is increased, and the safety and the transportation efficiency are reduced.
The linear vortex brake is a non-contact electromagnetic brake mode, does not depend on wheel track adhesion, can exert larger braking force in a high-speed section, can be used for emergency braking and service braking, can effectively shorten the braking distance and improve the running safety, has the outstanding advantages of no mechanical abrasion, no noise, no smell, controllable braking force and the like, can reduce the abrasion of mechanical braking, has good running economy, and is particularly suitable for a high-speed train braking system.
The linear eddy current brake is also called as rail eddy current brake, and its basic principle is that bar magnet for braking is mounted on the bogie of railway vehicle and is positioned over the steel rail, the N, S poles of the magnet are alternatively arranged, the bottom surface of magnetic pole and top surface of steel rail are kept a certain working air gap, and the steel rail is used as magnetic induction body. By utilizing the relative motion of the magnet and the magnetic inductor, an electric vortex (eddy current for short) is induced in the steel rail, the magnetic field generated by the vortex interacts with the main magnetic field generated by the magnet and causes the main magnetic field to generate distortion, magnetic force lines deflect, and tangential component force (namely braking force) is generated, so that the train is decelerated, and the braking energy is converted into eddy current loss of the steel rail. The braking force generated by the linear vortex brake device directly acts on the bogie without being limited by wheel track adhesion, so that the brake device has obvious braking effect in a high-speed section.
Since the end of the 60 s of the 20 th century, the application of eddy current braking technology on passenger trains has been studied by law, germany, day, etc., and tested for many years. Since 2002, the linear vortex brake device is commercially applied in batches on ICE3 high-speed trains in germany, and good application effect and economic benefit are obtained. At present, due to the limitations of factors such as technology and cost, the linear vortex brake engineering application of the high-speed train is not realized in China.
The linear vortex brake device mainly comprises electromagnet, support arm, transverse pull rod, suspension unit and dowel bar component, wherein the electromagnet is used for establishing electromagnetic field and structural load, the suspension unit hangs the vortex brake device on the bogie when the vortex brake is released, the support arm plays the role of vertical positioning and support when the vortex brake is applied, the transverse pull rod connects two groups of vortex brake electromagnet into a whole, and the dowel bar component is used for transmitting vortex brake force to the bogie.
The linear vortex brake device has large dead weight, the height of the electromagnet is limited by the space of the bogie, and the vertical rigidity of the magnetic yoke is limited. When the device is in a working state (braking is applied), under the multiple actions of dead weight, electromagnetic attraction and vibration impact, the magnet yoke of the electromagnet can generate larger vertical deflection deformation, so that the damage such as unstable eddy current braking force, collision of magnetic poles with steel rails and even damage of the magnetic poles is easily caused, and the driving safety is influenced.
