Chinese abstract:
      雪车空气动力特性对比赛的结果起着非常重要的作用。为提高运动成绩,需优化雪车空气动力,使其气动阻力尽量减小。国外学者主要是通过计算流体动力学(computational fluid dynamics,CFD)数值模拟、风洞实验等方法来研究雪车空气动力特性以及优化减阻方法,但国内尚未开展相关研究工作。系统地梳理近20年来雪车项目空气动力学研究成果,主要包括雪车外形以及运动员位置与姿态等参数气动优化的数值模拟与风洞实验,以期对雪车项目气动优化减阻技术要求有一个清晰的认识,并提出雪车项目空气动力学研究未来可能的发展方向:雪车项目空气动力优化系统性研究以及空气动力减阻效果的全面评估;运动员滑行操控与雪车空气动力的相互影响研究。这些研究结果将为雪车项目运动装备优化改进以及运动员日常训练提供重要的科学指导。

      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 computational fluid dynamics (CFD) numerical simulation, wind tunnel experiments and other methods to study the aerodynamic characteristics and optimize drag reduction method, but the relevant research has not yet been carried out in China. In order to have a clear understanding of the technical requirements of bobsleigh aerodynamic optimization and drag reduction, the research result of bobsleigh aerodynamics in recent 20 years have been systematically combed, mainly including numerical simulations and wind tunnel experiments of aerodynamic optimization of bobsleigh body shape and athletes’ positions and attitudes in the bobsleigh, and the possible future development direction of bobsleigh aerodynamics research has been put forward: the systematic study of bobsleigh aerodynamics optimization and comprehensive assessment of bobsleigh aerodynamic drag reduction effects; the study on the interaction between athlete glide control and bobsleigh aerodynamics. These studies will provide an important scientific guidance for the optimization and improvement of bobsleigh sports equipment and the daily training of athletes.
