Aerodynamic brake is a new type of non-adhesion brake mode used to high-speed train brake by unfolding the brake panel on the roof of the high speed train to increase aerodynamic resistance. This brake mode is effective especially in the condition of high speed. The article is aimed at designing a set of opening and closing mechanism to control the movement of the brake panel. The opening and closing mechanism mainly include three components of guide mechanism, the center of rotation and drive mechanism. The guide mechanism as auxiliary orientation is a functional unit of the bearing parts used to improve the movement and load conditions of the brake panel. The center of rotation is the key component to support the brake panel and transmit the braking force. The drive mechanism, the power source of the opening and closing mechanism, is designed to drive the brake panel up and down in the reciprocating motion. This paper focuses on the design of the three components, using the method of combining structural design and reliability design and aiming at the final optimal design.
