| 摘 要： | 车身造型直接决定了汽车在行驶过程中受到的空气阻力的大小。将汽车的后视镜和门把手内置能使车身整体更加符合流线型,降低约3%的整车迎风面积,从而减少汽车在行驶过程中受到的空气阻力。本研究运用Pro/Engineer造型功能建立三维模型,在Hypermesh对模型的流场计算域进行网格划分,然后将网格导入Fluent中进行仿真计算。经过对后视镜和门把手内置模型与后视镜和门把手外置模型的比较分析,得出后视镜和门把手内置能有效的降低汽车的风阻系数,减少汽车在行驶过程中受到的空气阻力。

| Abstract: | Body styling directly determines the degree of the air resistance when the car is on the run. Building-in the rearview mirror and door handle will enable the whole construction of the car to be more consistent with the streamline, reducing about 3% of the head-on wind area. This research utilizes the function of Pro/Engineer to build a 3D model, and do meshing by Hypermesh, then guide the mesh into Fluent to carry out simulated calculation. Comparative comparisons are made between the simulated results of building-in the rearview mirror and door handle and that of building-outside ones to conclude that building-in the rearview mirror and door handle can effectively reduce the drag coefficient and the degree of the air resistance when the car is on the run.. |
