The current technology can keep rail trains running at medium and low speeds, but when the trains are running at high speeds, only non-adhesive braking can be used

At present, the common non-adhesive brakes suitable for high-speed rail trains include eddy current brakes and magnetic rail brakes. However, while ensuring high-speed operation, the friction coefficient between the magnetic rail brake and the track contact surface is greatly reduced, resulting in braking force Obviously insufficient, so that the braking requirements cannot be met, so it is necessary to design a special braking device to meet the braking requirements of high-speed trains
