| 摘 要： | 目的：探究不同风速对帆板帆翼结构以及周围流场的影响。方法：以奥运女子级别的Neil Pryde RS：X帆板帆翼为研究对象，考虑空气动力与结构的流固耦合效应，利用ANSYS Workbench进行单向流固耦合分析。结果：Realizable模型适合计算帆翼周围的流场湍流度，在风速为2m/s时帆翼升阻比最大；随着风速的增大，帆翼面发生变形和振动会导致风激振现象、背风面产生明显的涡脱现象，且帆翼表面应力区增大，全帆的应变逐步增加。结论：不同风速下的帆翼迎风面和背风面的压力分布、帆翼整体空气动力有一定差异，运动员比赛中应该根据当时风况调整帆翼参数。

| Abstract: | In order to explore the influences of different wind speeds on the sail wing of a windsurfer structure and the surrounding flow field, the sail wing of the Neil Pryde RS:X that was an Olympic women's class was taken as the research object. The aerodynamic performance of a sail wing for Neil Pryde RS:X at different wind speeds was carried out by ANSYS Workbench based on unidirectional Fluid-Structure Interaction. The results showed that the lift-drag ratio of the sail wing was the largest when the wind speed is 2 m/s; The deformation and vibration of the sail wing would lead to wind-induced vibration and obvious vortex phenomenon on the leeward side, and the stress area of the sail wing surface would increase and the strain of the whole sail would gradually increase as the wind speed increased. The Realizable k-ε model was used to calculate the turbulence. The pressure distribution on the windward and leeward sides of the sail wing, the overall aerodynamic force of the sail wing and its variation law were obtained by the numerical simulation of the sail wing at different wind speeds. The athletes should scientifically adjust their sail wings in the sailing regatta. |
