The invention provides an automobile body front structure and an automobile, the automobile body front structure comprises a front windshield, an A column and front side window glass, the front windshield is arranged on the Y-direction inner side of the A column, and the front side window glass is arranged on the X-direction rear side of the A column; through the structural arrangement of the front windshield, the A column and the front side window glass, an airflow separation area is formed on the A column, and a low-wind-noise structure is arranged on the airflow separation area. According to the invention, the low-wind-noise structure is arranged on the airflow separation area of the column A, the low-wind-noise structure enables the surface of the airflow separation area of the column A to become relatively rough, and compared with a smooth surface, the rough surface can better change airflow movement near a wall surface; the non-smooth surface design transformation is carried out on the airflow separation area of the A column, so that the airflow separation condition in the airflow separation area of the A column can be improved, the airflow separation is further weakened, the wind noise intensity brought by the airflow separation in the airflow separation area of the A column is finally reduced, and the noise pressure on the front side window glass can be weakened.
本发明提供了一种车身前部结构及汽车,该车身前部结构包括前挡风玻璃、A柱和前侧窗玻璃,前挡风玻璃设置在A柱的Y向内侧,前侧窗玻璃设置在A柱的X向后侧;前挡风玻璃、A柱和前侧窗玻璃的结构布置,使A柱上形成气流分离区域,气流分离区域上设有低风噪结构。本发明中,在A柱的气流分离区域上设有低风噪结构,低风噪结构使A柱的气流分离区域的表面变得相对粗糙,粗糙表面与光滑表面相比可以更好的改变近壁面气流运动;即对A柱的气流分离区域进行非光滑表面设计改造,可以改善A柱的气流分离区域内的气流分离情况,进而减弱气流分离,最终降低A柱的气流分离区域内气流分离所带来的风噪声强度,可以减弱前侧窗玻璃上的噪声压力。
