构建了速度滑冰“人体-冰刀-环境”复杂多自由度体系空气动力学模型。利用3Ds Max重构速度滑冰运动员实际比赛场景，提取运动员在弧顶典型技术动作，并通过Geomagic Wrap和ZBrush逆向工程及图形雕刻软件加工速度滑冰模型，利用ANSYS mesh构建数值网格模型，利用Navier-Stokes（N-S）方程描述速度滑冰多自由度体系湍流演化分布，并利用Tecplot开展度滑冰空气流场压力分布和速度分布的可视化分析，实现速度滑冰“人体-冰刀-环境”复杂多自由度体系空气动力学模型的构建。

A complex multi-degree-of-freedom system aerodynamic model of speed skating "body-skate-environment" was constructed. The speed skater's actual game scene is reconstructed by 3Ds Max, and the typical technical movements of the skater at the top of the arc are extracted, and the speed skating model is processed by Geomagic Wrap and ZBrush reverse engineering and graphic sculpting software, and the numerical mesh model is constructed by ANSYS mesh, and the Navier-Stokes (N-S) equation is used to describe the turbulence evolution of the speed skating multi-degree system. The model is constructed by using ANSYS mesh, the Navier-Stokes (N-S) equation is used to describe the turbulence evolution distribution of the multi-degree of freedom system of speed skating, and Tecplot is used to visualize the pressure distribution and velocity distribution of the air flow field of speed skating.
