technical field

Background technique

At present, the trains in our country mainly adopt the braking method of mechanical friction. Due to the high speed of the train before braking, there is a lot of friction between the brake device and the train, which causes the wear of the brake device and the wheels, and requires frequent repairs and maintenance. Therefore, How to improve braking efficiency and improve braking performance has become a problem that continues to be solved now.

Secondly, the mechanical friction when the train brakes means that the huge mechanical energy of the train can only be dissipated through the mutual friction between the wheels and the brake pads into heat energy, which greatly wastes energy. At present, there are almost few equipment and technologies for recovering the mechanical energy of train braking.
