摘要

滑行阶段的风阻力是影响雪橇项目竞技成绩的重要因素，根据雪橇国家集训队10名运动员的风洞测试结果，对雪橇项目在滑行阶段的风阻力特性进行了研究，为提高该项目的竞技水平提供了支持。测试结果表明，当滑行速度超过20 m/s时，雪橇运动员风阻面积系数

的雷诺数效应可以忽略；受窄道效应影响，风洞测试中增加赛道后，雪橇运动员受到的风阻力增加12%；运动员抬头调整滑行线路时，风阻力将增加16%，将头部倾斜有利于减小风阻力的不利影响，此时，风阻力仅增加10%；绷脚尖和翘脚尖姿态下的风阻力相差27%，对成绩影响很大，运动员应尽量保持脚尖绷紧，在绷脚尖的同时，将小腿下倾有利于减小风阻力。

Abstract

The aerodynamic drag of luge athletes during gliding is an important factor in improving the performance of the luge competition. Based on the wind tunnel test results of 10 athletes of the National Luge Team

the aerodynamic drag characteristics of the athletes during gliding are studied. The results show that the Reynolds number effect on the drag area coefficient (

) of the athletes can be ignored during sliding when the sliding speed exceeds 20 m/s. The aerodynamic drag is increased by 12% after installing the track due to the narrow tunnel effect. When athletes raise their heads to adjust the gliding line

the aerodynamic drag can be increased by 16%

but tilting their

heads can help reduce the negative effect on the aerodynamic drag

with the aerodynamic drag only increased by 10%. There is 27% difference in the aerodynamic drag between the toe-tight position and the toe-up position

which can have a great effect on the performance of the athletes. In addition

lowering the calf while keeping the point toes position is an effective way to reduce the aerodynamic drag for the luge athletes.
