泡沫铝材料用于减振、吸声结构的初步设计

Primary Design for Composite Structures by Using Aluminum Foam as Damping or Sound Absorption Materials

针对日益突出的噪声污染问题,以风机室的降噪处理为例,较详细地介绍了风机减振结构的设计方法、风机吸、排风口消声结构的设计方法和风机室整体的减振、隔声和消声结构的设计方法,同时给出了设计依据的基本原理。目的在于为解决工业企业的噪声污染问题提供一条新的途径,同时推动泡沫铝材料在我国的实际应用。

The design methods of damping structure used for the ventilator foundation, noise reduction structure connected to the air suction or exit holes of ventilators and sound isolation or absorption struc- tures used in the whole fan room are introduced in this paper, which are helpful to control the transmission of fan room noises, and the basic principles of design are also provided. The paper can offer a new ap- proach for industrial enterprises to solve their noise pollution problems and promote the practical applica- tions of aluminum foam in our country.
