降低整机噪声的方法很多,常用的方法是首先找出噪声声源,然后尽可能降低声源噪声,在无法继续降低或降低声源噪声不经济的情况下,就采用吸声方法和抑制噪声传播的方法。本文介绍加强箱体例壁刚性来抑制声波和机械振动对箱体激振而降低噪声的方法。 一般在设计机床 箱体时,对结构 There are many ways to reduce the noise of the whole machine. The commonly used method is to find out the noise source first, and then to reduce the noise of the source noise as far as possible. Under the circumstance that it is not economical to continue to reduce or reduce the noise of the sound source, the sound absorption method and the noise suppression Methods of communication. This article describes ways to increase the stiffness of the enclosure wall to suppress acoustic and mechanical vibrations on the enclosure and reduce noise. General design of the machine box, the structure
