FSC赛车空气套件CFD优化设计

在满足FSC赛车设计规则要求前提下,对空气套件进行了结构优化设计,重点完成了赛车尾翼的优化设计和分析。利用CFD技术对赛车车身模型进行了外流场分析,并通过在赛车尾部加装不同间隙和攻角的尾翼,进行车身外流场模拟对比分析,研究尾翼在改善赛车气动特性方面的影响规律,研究确定了空气动力学装置在不同比赛项目时的调教策略。通过对比分析赛车车辆周围气流的压力分布和速度分布规律,研究高速赛车的负升力效果,对于提高赛车的操纵稳定性和安全性具有非常重要的意义,对于指导赛车尾翼的正确安装、确定尾翼在不同比赛项目时的调教策略有一定的指导意义。

The Structural Optimal Design for the air kit of FSC racing car Based on CFD

under the premise of meeting the FSC racing car design rule requirement, the air kit structural optimization design is completed, focusing on the completion of the racing wing optimization design and analysis. First, CFD software FLUENT is used for car body model for the flow field analysis, and through adding the wing of different attack angle and clearance at the end of the car and carry out comparative analysis of body flow field simulation to study the aerodynamic characteristics of the wing in improving aspects of racing law, the study identifies the aerodynamic devices on different events when tuning strategies. Through comparative analysis of the airflow around the vehicle racing pressure distribution and velocity distribution of high-speed racing of negative lift effect, for improving the car＇s handling and stability and security has a very important significance for guiding racing wing installed correctly identified in the wing different events when tuning strategy has certain guiding significance
