摘要

结合车辆风噪声机理和整车声学风洞试验实例,分析了玻璃隔声、整车密封、偏航对整车风噪声的影响,以及不同速度下的车辆风噪声频谱特征与整车道路风噪声之间的关联。试验表明,整车声学风洞试验对于整车风噪声性能的评估和优化有着重要意义。
        Combining the wind noise mechanism with the wind tunnel test,the paper analyzed the influences of the sound insulation of glass,vehicle insulation,yaw angle and wind speed on wind noise performance. The results show that the wind noise test in a wind tunnel is of great importance for the evaluation and optimization of the vehicle wind noise performance.
