摘要
针对某SUV车型风噪产生机理进行研究,利用声学风洞开展车身表面噪声源测试、噪声源定位试验及车内风噪试验,并通过分析试验数据确定了风噪影响因素及部位。最后,通过研究隔声玻璃阻尼损耗因子及隔声性能,发现隔声玻璃的运用可以有效降低车内风噪水平,是一种优化车内噪声的重要手段。
This article mainly studied a certain SUV’s generating mechanism of wind noise. By using the acoustic wind tunnel, the research carried out noise source test of car body surface, the location test of noise source and the test of interior wind noise. And through analyzing the test data, the study found out the influencing factors and specific position of wind noise. Finally, by researching and testing the damping loss factor and sound transmission loss of the sound insulation glass, the research found that application of the sound insulation glass can effectively reduce interior noise.
