摘要

对现代f1赛车中使用的三种不同类型的前翼设计进行了基于仿真的研究。主要研究f1赛车在低速转弯时产生的空气动力,主要是下压力、阻力和侧向力。我们对这些力进行了详细的研究,并仔细观察了它们在赛车以各种侧滑(偏航)角度抛出时的动态情况下是如何迁移的,并将这些结果与法拉利车队在1998年一级方程式锦标赛中使用的机翼进行了比较,以更好地理解之前设计中面临的固有问题。对三个机翼的流场和流线进行了简要的研究,并对涡的产生进行了分析。涡流的形成与管理是f1赛车研究的重点,因此对涡流的产生现象和Y250涡流的形成也进行了简要的研究。研究了不同高度下的飞行高度和涡量的变化规律,并进行了数值分析。研究了上单元流场对下单元流场的影响,其中从三个机翼中分别移除第5个单元,并分析了下压力和阻力值的影响以及压力场。

Studying Modern Formula 1 Front Wing at Low Cornering Speeds
A simulation-based study of three different types of front wing designs used in the modern Formula 1 cars was done. The study mainly focuses on the aerodynamic forces that a Formula One car generates mainly the Downforce, the Drag force, & the Lateral force at low cornering speeds. These forces were studied in detail & taking a closer look at how they migrate during the dynamic conditions the car is thrown at various Side Slip (Yaw) Angles, these results were compared with the wing Scuderia Ferrari used in the 1998 formula 1 championship to better understand the inherent problems faced in those previous designs. A brief study of the flow field & flow lines was conducted along with the vortex generation for all three wings. Vortex formation and management is a prominent part of research being carried out for a formula 1 car, so a brief study on the phenomenon of vortex generation & Y250 vortex formation was also carried out. A test on ride height and vorticity was also studied when the ride height was varied and the values were analysed. A study on the effect of the flow field of the upper element on the lower element was carried out where the 5th element was removed from each of the three wings & the effect on the downforce & drag value was analysed along with the pressure field.
