    Abstract:

    The aerodynamic characteristics of bobsleigh play a very important role in the result of the race. In order to improve the performance, it is necessary to optimize the bobsleigh aerodynamics and reduce its aerodynamic drag as much as possible. Foreign scholars has mainly used CFD numerical simulation, wind tunnel experiments and other methods to study the aerodynamic characteristics and optimize drag reduction methods, but the relevant research has not yet been carried out at home. In order to have a clear understanding of the technical requirements of bobsleigh aerodynamic optimization and drag reduction, the research results of bobsleigh aerodynamics in recent 20 years have been systematically combed, and the possible future development direction of bobsleigh aerodynamics research has been put forward: 1) the systematic study of bobsleigh aerodynamics optimization, explore and master the influence mechanism of bobsleigh body shape, the gap distance between the bottom of bobsleigh body and the ice surface of track, the position and attitudes of athletes in the bobsleigh on the aerodynamic drag, and comprehensively evaluate aerodynamic optimization effect; 2) study on the interaction between athlete glide control and bobsleigh aerodynamics. These studies will provide important scientific guidance for the optimization and improvement of bobsleigh sports equipment and the daily training of athletes.
