摘要：
For the problem of no unified standards for aerodynamic braking test methods for high-speed trains, the relevant achievements and developments in aerodynamic brake were systematically reviewed in two aspects from aerodynamic characteristics and device functional characteristics. The effects of the shape, size, position, and spacing of wind panel on the aerodynamic characteristics and the effects of the structure, working principle, and configuration of the device on the functional characteristics were analyzed. The test requirements for the braking system performance were clarified. The impacts of aerodynamic braking on other equipments in the vehicle, operational stability of wheel-track/maglev train, and aerodynamic noise were analyzed. In addition, the test requirements for the operational impact of the aerodynamic brake were determined. The effects of object impact, average wind load, and pulsating wind load on the aerodynamic braking devices and the effect of the device installation on the structural strength of vehicle were analyzed. Furthermore, the test requirements for the structural strength of the aerodynamic brake were clarified. Analysis results show that with the application of a new composite wind panel, further detailed information regarding the bird striking test process should be recorded by using a high-speed camera. Aerodynamic load test is convenient to simulate and verify braking capacity, strength and aerodynamic noise of the device under different operating conditions. However, it is difficult to test the braking system and car body because of space and cost constraints. Field tests can verify the braking system performance, operational impact, and structural strength, but it is challenging to simulate all operating conditions, limited by weather conditions. Further investigations of the standard test methods of aerodynamic brake are required, ground wind loading test and field test simulation methods for determining different device locations, operating conditions, and fault states are explored, and the evaluation standard of test results is improved. 4 tabs, 11 figs, 55 refs. © 2021, Editorial Department of Journal of Traffic and Transportation Engineering.
