“…This test was carried out in the Automotive Wind Tunnel Laboratory of Jilin University. The FSAE racing car was placed in the open test section, and the overall layout scheme of four-wheel support was adopted [21,22]. The racing car model is shown in First, the aerodynamic six-component force of the FSAE racing car was measured under linear conditions.…”

With the rapid development of FSAE, the speed of racing cars has increased year by year. As the main research content of racing cars, aerodynamics has received extensive attention from foreign teams. For racing cars, the aerodynamic force on the aerodynamic device ultimately acts on the tires through the transmission of the body and the suspension. When the wheel is subjected to the vertical load generated by the aerodynamic device, the ultimate adhesion capacity of the wheel is improved. Under changing conditions, racing wheels can withstand greater lateral and tangential forces. Therefore, the effects of aerodynamics have a more significant impact on handling stability. The FSAE racing car of Jilin University was taken as the research object, and this paper combines the wind tunnel test, the numerical simulation and the dynamics simulation of the racing system. The closed-loop design process of the aerodynamics of the FSAE racing car was established, and the joint study of aerodynamic characteristics and handling stability of racing car under different body attitudes was realized. Meanwhile, the FSAE car was made the modification of aerodynamic parameter on the basis of handling stability. The results show that, after the modification of the aerodynamic parameters, the critical speed of the car when cornering is increased, the maneuverability of the car is improved, the horoscope test time is reduced by 0.525 s, the downforce of the car is increased by 11.39%, the drag is reduced by 2.85% and the lift-to-drag ratio is increased by 14.70%. Moreover, the pitching moment is reduced by 82.34%, and the aerodynamic characteristics and aerodynamic efficiency of the racing car are obviously improved. On the basis of not changing the shape of the body and the aerodynamic kit, the car is put forward to shorten the running time of the car and improve the comprehensive performance of the car, so as to improve the performance of the car in the race.

“…Despite the fact that user experience and efficient human–machine interfaces are of great significance in the automotive industry, only a few academic attempts to use VA in varying depth exist. So far they have been mostly engaged in the domain of computer‐aided‐design [22], artificial vision [23], vehicle collision [24, 25], engine multibody dynamics [26], virtual reality [27], aerodynamics [28], sensor data [29], and electric vehicle (EV) charging analysis [30]. Additionally to the previous references, it is worth highlighting the contributions performed in [20] regarding the systematic deployment of visualisation systems for vehicle communication networks in a large automotive company.…”

There is a great demand for a new car model that can meet the needs of today’s research about vehicle aerodynamics due to the limitations of models used in the past. This paper focuses on the introduction of a new realistic car model and discussions about the model’s first experimental and simulation results. The new car model is designed to have a sensor-measuring function, and has four different back shapes. Specifically, the SUV back and the Pickup back are groundbreakingly designed in combination with Chinese aerodynamic design trend. The experiments were performed in a full-scale aero-acoustic wind tunnel with ground simulation system, consisting of boundary layer control system and five-belt system. Base on the wind tunnel experimental results, it can be found that the ground simulation has obviously influence on the drag coefficient, but has no influence on the distribution of surface pressure in upper body. The close state of the grilles, the absence of mirrors, and the fully enclosed of rims can significantly reduce the drag coefficient. Digital wind tunnel (DWT) simulation and open road (OR) simulation have been completed and verified with experimental results. It can be concluded that DWT simulation with the same geometry as the real wind tunnel performs better than the OR simulation. The maximum difference between the experimental results and the DWT simulation results does not exceed 2% and DWT simulation also performs well in the surface pressure simulation.
