摘要
基于声振理论与实验分析技术，系统研究了金属锯切过程的动态特性，提出快速方便地估算任一夹紧比下弹性圆板结构动态特性的算法。进而探索了减振降噪措施，取得明显降噪效果。
Based upon theoretical and experimental methods of acoustics and vibration, the dynamic characteristics of cutting processes have been researched systematically, and a simplified method of quickly estimating the modal parameters of elastic circular plate structures under clamping has also been advanced. Furthermore, we try the best to explore effectively the noise-reducing ways in the sawing process. In fact, satisfactory results have been achieved in practice.
