摘要
赛车的车身造型对其空气阻力、操纵稳定性、加速性及燃油经济性等性能有着很大的影响。运用CATIA软件根据FSEC赛车规则对车身进行造型设计,并利用CFD技术建立其外流场模型进行数值模拟分析,获得其压力云图、速度矢量图等。总结该赛车造型的气动特性的优缺点,为后期赛车车身的设计定型提供理论依据。
The body shape of the car has a great influence on the car’s body wind resistance,handling stability,acceleration and fuel economy.This paper uses CATIA software to design the body according to FSEC racing rules,and uses CFD technology to establish its external flow field model to carry out numerical simulation analysis,obtains its pressure cloud map,speed vector diagram,etc.,summarizes the advantages and disadvantages of the aerodynamic characteristics of the car.It provides a theoretical basis for the later design of the racing car body.
