【 摘 要 】

According to the recovery requirement of high-speed double-track sled, the horizontal momentum conversion type water brake structure is designed, the brake resistance is calculated. The brake resistance under six working conditions is calculated by using the calculation model of horizontal momentum conversion water brake force. The brake resistance is calculated by using FLUENT software. The force is simulated and checked. The results show that the brake resistance calculated by the two methods are basically identical, which provides support for the development of high-speed double-track sled.
