汽车侧窗风振噪声分析与改进
|
摘要
以某乘用车为研究对象,采用实车道路试验和仿真分析的方法,研究不同侧窗开启组合下驾驶员耳旁的风振噪声和侧窗风振噪声产生的机理,并提出在后视镜支撑臂位置开槽抑制风振噪声的措施,降噪可达7 d B。
Taking a passenger car as the research object,the authors use the methods of real vehicle road test and simulation analysis to study the buffeting noise at driver's ear under different combination of side windows opening and the mechanism of buffeting noise generation on side windows,then propose a measure of grooving on the side rear view mirror arms to decrease the side windows buffeting noise. The noise decreasing result is 7 d B.
