铝蜂窝夹层材料在客车噪声控制的应用研究

Researches on Aluminum Honeycomb Sandwich Material for Noise Control in Coaches

铝蜂窝夹层材料是一种采用铝箔和高强度胶黏剂制造的具有蜂窝孔结构的多功能复合材料。针对某客车车内噪声水平较大的问题,采用一种铝蜂窝夹层材料,在综合运用吸声、阻尼、隔声技术的基础上,实现控制客车车内噪声的目的。

Aluminum honeycomb sandwich material is a multifunctional composite material with a honeycomb structure of aluminum foil and manufactured by high strength adhesive. Focusing on the problem of the coach interior noise, on the basis of the integrated use of sound absorption, sound damping, sound insulation, an aluminum honeycomb sandwich material was used to achieve the purpose of controlling the coach interior noise.
