摘　　要：为研究滑雪运动员所受的空气阻力特性,在风洞中设计一种阻力特性的实验测量方法。在采用天平测量运动员所受空气阻力的同时,通过图像采集与处理获取运动员的迎风投影面积,进而计算出其对应的阻力系数。运动员在风洞中模拟不同的运动姿势,获取各姿势下的数据。实验结果表明:随着人体从站立到蹲下,空气阻力和阻力系数呈减小的趋势,半蹲姿势阻力特性最为稳定,且阻力系数较小。该方法可为训练提供参考建议与指导。In order to study the characteristics of air resistance experienced by skier,an experimental measurement method for resistance characteristics has been designed in the wind tunnel.While measuring the air resistance of skier by balance,the windward projected area of skier is obtained by image acquisition and processing,and then the corresponding resistance coefficient is calculated.The skier simulated different postures in the wind tunnel and obtained the data of each posture.The experimental result shows that the air resistance and resistance coefficient decrease as the human body changes from standing to squatting,and the resistance characteristic of the half squatting is the most stable and the resistance coefficient is small.This method can provide reference and guiding for training.
