多层复合材料隔声在洗碗机中的应用

Application of multilayer composite materials in dishwashers

传统洗碗机中采用吸音棉进行降噪,但在设计上存在缺陷,导致降噪材料性能无法有效发挥。本文中根据多层隔声理论分析,优化了吸音棉与钣金材料的安装方式,以多层隔声结构的方式,实现降噪效果的最大化。本研究内容不仅针对洗碗机方案设计,也对同类产品的噪声改善起到指导作用。

The traditional dishwasher using sound-absorbing cotton for noise reduction, but the defects in the design, material performance can't effectively play a lead to noise reduction. In this paper, according to the analysis of multi-layer sound insulation theory, the installation mode of sound absorbent cotton and sheet metal material is optimized, and the noise reduction effect is maximized by means of multi-layer sound insulation structure. This study not only has a guiding effect on the design of dishwasher scheme, but also on the improvement of noise of similar products.
