速滑服风致减阻效能评价方法

Evaluation Method of the Speed Skating Suits' Wind-induced Drag Reduction Efficiency

针对速滑服风致减阻效能的优劣,分析了身着速滑服运动员模型风致阻力的组成,提出了分别基于风洞试验以及材料表面微观几何特征观测的速滑服减阻效能评价方法,并进行速滑服的减阻效能评价试验。试验表明,具有较低的材料表面轮廓算数平均偏差值的速滑服减阻效能优异,试验也相互验证了两种比赛服减阻效能评价方法的可靠性。

Aiming at the speed skating suits wind - induced drag reduction efficiency, the paper analyzes the factors of speed skating suits＇wind - induced drag in skater models. It puts forward the evaluation meth- ods of speed skating suits drag reduction efficiency respectively basing on wind tunnel test and surface micro geometrical structures analysis. And it has an experimental evaluation of speed skating suits drag reduction efficiency. The results show that the suit with lower outline arithmetic average deviation has more excellent drag reduction efficiency, and the tests also prove the evaluation methods reliability.
