研究了速度滑冰冲刺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冲刺阶段人体和冰刀的整体流场特性及压力分布的数值计算，分析了速度滑冰冲刺阶段运动员在“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 human body and ice skates during the sprint phase of speed skating were studied. Based on the aerodynamic model of the complex multi-degree-of-freedom system of "human body-skate-environment", the numerical calculation of the overall flow field characteristics and pressure distribution of human body and ice skates during the sprint phase of speed skating was carried out by using FLUENT software, and the resistance and distribution characteristics of athletes in the "human body-ice skate-environment" complex multi-degree-of-freedom system during the sprint phase of speed skating 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.
