Dynamic behavior of high speed train is very important because the high speed train should be safe and satisfied with the ride comfort. An eddy current brake system is mounted on trailer bogie and wheel set. The eddy current braking force longitudinally exerts on the articulated trailer bogie and the attraction force vertically exerts on the wheelset. Because a frame of eddy current brake system is flexible, these forces generate the vertical vibration at middle point of the frame. Also, the vibration change the vertical clearance between an electromagnet and top of rail which affect the magnitude of braking and attracting forces. Therefore, the dynamic behavior of the eddy current braking system must be predicted for design the dynamic characteristic of its mounting system when normally operate on rail which have irregularity. Vampire program is used for prediction of the dynamic behavior of an eddy current braking system.

Air brake system of KTX effectively distributes air to brake panel in each bogie. System consists of carrying bogie brake panel motor bogie brake panel driver's valve panel pneumatic auxiliary panel and other accessories. For the prove endurance confirm test number. Distributor and control moderable magnet valve are 500,000 times and respectively carrying bogie MR/BP cut-out cock are 12,000 times. Tests satisfy all of condition until now. Developments conduct a performance test to brake tester of domestic manufacturer and operating authority.
