摘要：

Based on the wind tunnel test of a type of car, the influence of 5 different tires and 3 rims on the aerodynamic performance of the vehicle and their interaction are studied, and the PIV (Particle Imaging Velocimetry) is used to measure and compare the flow field near the wheels. The results show that the difference of drag and lift coefficient among tires with different tread patterns is up to 0.003 and 0.026 respectively, and the difference varies with the rim design. Then the deformation of different tires under rotation is measured by the image recognition, in order to reproduce the correct tire geometry for simulation and calculation. By comparing the results of simulation and test, the reasons for the difference of aerodynamic performance caused by tires with different tread patterns are analyzed, which provides guidance for the wheel aerodynamics development. © 2021, Society of Automotive Engineers of China.
