某乘用车外后视镜处风噪的分析及改进

Analysis and Improvement on Wind Noise in the Rearview Mirror of a Passenger Car

在分析某乘用车高速行驶时前侧门处外后视镜产生风噪的基础上,提出设计优化方案,为驾驶员及乘客提供安静的环境,进而提升整车驾驶的NVH。

Based on the analysis of the wind noise generated by the external rearview mirror at the front side door when the passenger car is driving at hige speed,the optimization solution is proposed,which provides a quiet environment for drivers and passengers,and enhances the vehicle NVH.
