| Abstract: | Sunroof buffeting noise issue of automobiles due to wind load is introduced. Its mechanism is elaborated. Two approaches suppressing buffeting noise are proposed： installing wind deflector web and reducing opening size of the sunroof. Designs of wind deflector web and traditional wind deflectors are compared each other. Both approaches are tested in wind tunnel, and good results are obtained. Finally, the two approaches are summarized and further study is predicted. |
