把喷水阻尼技术首次用于大型圆盘金属锯机的减振降噪 ,通过对其降噪效果及频谱的测量分析 ,发现对于锯切噪声的降低 ,喷水阻尼不但是一种简单实用的技术而且降噪效果显著 ,且由此引起的附加噪声比较小
The water jet damping technology is firstly applied to the vibration reduction and noise reduction of the large disc metal sawing machine. Through the noise reduction effect and spectrum measurement analysis, it is found that the water jet damping is not only a simple and practical method for reducing the sawing noise Technology and noise reduction effect is significant, and the resulting additional noise is relatively small
