摘　　要：基于FSAE赛事,通过CFD分析方法设计并优化尾翼端板形状,并总结出一套碳纤维复合材料端板加工流程以提升尾翼的气动效率和刚度表现。首先,根据后处理云图、流线图的变化规律和匹配原则,结合数字化设计过程,确定了大曲率端板外形最佳方案,以减小前部空气动力学装置及驾驶舱湍流尾迹对流经尾翼气流的干扰,并在端板下部分设置尾翼整体部件的额外支撑点,拟达到优化流场和尾翼结构刚度、提升装置机械稳固性的目的。随后,制作成品并总结出一套完善的碳纤维复合材料尾翼端板制备方案,证明相关设计的可行性。Based on the FSAE competition,the CFD analysis method was used to design and optimize the shape of the wing endplate,and a set of carbon fiber composite endplate manufacturing processes was summarized to improve the aerodynamic efficiency and performance of the wing.Based on the changes in the postprocessing cloud map and streamline map,and the matching principles,the best solution for the large curvature endplate shape was determined through the digital design process to reduce the interference of the turbulence wake of the front device and cockpit on the airflow passing through the wing,and additional support points for the overall wing component were set at the lower part of the endplate to optimize the flow field and wing structure stiffness and improve the mechanical stability of the device.Subsequently,a finished product was produced and a carbon fiber composite wing endplate preparation scheme was summarized to demonstrate the feasibility of the related design.
