摘要
以汽车实际开发过程中为了降低风阻系数和风噪大小,通过对车身外造型进行外流场CFD分析,提出A柱造型的局部优化方向,然后再通过对车身A柱结构的不同分件形式、安装固定方式的可行性对比分析,选择最佳可实施的方案,通过在A柱与前风挡之间增加卡接的前风窗装饰条的方式实现A柱造型的局部优化来提升整车性能,降低风阻系数和风噪大小。
In order to reduce the wind resistance coefficient and wind noise in the process of automobile actual development, this paper puts forward the local optimization direction of A-pillar modeling through the CFD analysis of the external flow field of the automobile body styling, and then selects the best programmable scheme through the comparison and analysis of the feasibility of different parts from and installation fixed mode of the A-pillar structure. The local optimization of A-pillar modeling is realized by add the front windshield side garnish between the A-pillar and the front windshield to improve the vehicle performance, reduce the wind resistance coefficient and the size of wind noise.
