摘要
文章基于统计能量法(SEA)开展了声学覆盖层敷设位置对舱室噪声的影响研究,探讨了不同损耗因子对舱室噪声的影响,计算对比表明阻尼损失系数发生改变时,声学覆盖层的抑振降噪效果亦将发生改变。
In combination with SEA, this article, based on an analysis of the influence of the laying position of the acoustic layer on cabin noise, studies the influence of different dissipation factors on cabin noise, the results of which indicate that the changes of the damping coefficients have a great effect on the vibration damping and noise reduction of the acoustic layer.
