摘要
阐述了风振噪声的产生机理;介绍两个抑制风振噪声的手段,网状挡风条和减小玻璃打开开口大小,对网状挡风条与传统挡风条设计进行对比。试件在风洞中取得良好的试验结果;最后对设计中所采用的两个手段予以总结,对未来的研究工作进行展望。
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.
