研究了速度滑冰直行阶段人体和冰刀的整体流场特性。基于“人体-冰刀-环境”复杂多自由度体系空气动力学模型，利用FLUENT软件开展了速度滑冰直行阶段人体和冰刀的整体流场特性及压力分布的数值计算，分析了速度滑冰直行阶段运动员在“人体-冰刀-环境”复杂多自由度空气流场中的阻力及分布特征。

The overall flow field characteristics of the human body and the ice skates during the speed skating phase were studied. Based on the aerodynamic model of the complex multi-degree-of-freedom system "human body-skate-environment", the numerical calculation of the overall flow field characteristics and pressure distribution of the human body and the ice skates during the speed skating straight line phase was carried out by using FLUENT software, and the resistance and distribution characteristics of the athletes in the "human body-ice skate-environment" complex multi-degree-of-freedom system during the speed skating straight line phase were analyzed. The resistance and distribution characteristics of the athlete in the complex multi-degree-of-freedom air flow field of "body-skate-environment" were analyzed.
