The invention discloses a system capable of actively inhibiting wind vibration noise of an automobile window and an automobile. The system comprises automobile window glass and an automobile window sunshade curtain system capable of adjusting the mesh diameter and porosity parameters of sunshade curtain cloth in real time based on the opening value of the automobile window. Determining an opening value of the window glass of the vehicle based on the actual position of the window glass of the vehicle and the calibrated position of the window glass of the vehicle; based on the opening value of the vehicle window glass, the mesh diameter and porosity parameters of the vehicle window sunshade curtain system are obtained; the vehicle window sunshade curtain system completes adjustment of vehicle window sunshade curtain cloth based on the mesh diameter and porosity parameters. According to the method, the mesh diameter and porosity of the sunshade curtain cloth can be adjusted in real time, the flow field characteristics under each window opening degree can be matched in real time, and finally a good window wind vibration noise improvement effect is obtained.
本发明公开了一种可主动抑制汽车车窗风振噪声的系统和车辆,包括车窗玻璃和可基于车窗开度值实时调节遮阳帘帘布网孔直径和孔隙率参数的车窗遮阳帘系统,基于车辆的车窗玻璃的实际位置和车辆的车窗玻璃的标定位置确定车辆的车窗玻璃的开度值;基于车窗玻璃的开度值获取车窗遮阳帘系统的网孔直径和孔隙率参数;车窗遮阳帘系统基于网孔直径和孔隙率参数完成车窗遮阳帘帘布的调节。本发明可以通过实时调整遮阳帘帘布的网孔直径与孔隙率,实时匹配各个车窗开度下的流场特征,最终获得较好的车窗风振噪声改善效果。
