风洞声学环境对风噪测试结果的影响

摘 要：文章通过对同一车辆在环境风洞和气动声学风洞中分别进行风噪测试，对比并研究不同风洞声学环境对车内风噪测试结果的影响及相关频率特性；然后用风噪测试中最常见的两种工况分别在两种不同类型风洞中进行测试，对比结果并评价贡献量差异特性，为后续开展更深层次的相关测试进行铺垫。

Abstract：In this paper， the influence of different wind tunnel acoustic environments on the wind noise test results and related frequency characteristics of the same vehicle in the ambient wind tunnel and aeroacoustic wind tunnel are compared and studied. Then， the two most common working conditions in the wind noise test were tested in two different types of wind tunnels， and the results were compared and the difference in contribution characteristics was evaluated， which paved the way for further related tests in the future.

Key words：Wind Noise Test， Environmental Wind Tunnel， Aeroacoustic Wind Tunnel， Comparative Results， Difference in Contribution
