摘要

金属圆锯片属于面积较大的薄板类零件，其在锯切加工过程中普遍存在着严重的振动问题。为提高圆锯片的锯切性能，降低其工作时的振动，在对圆锯片振动分析及其试验模态理论研究和试验分析的基础上，对比两种不同基体结构圆锯片的固有特性，分析其固有频率及振型的变化，推断基体上开减振孔对锯片整体性能，尤其是对圆锯片振动特性的的影响。试验证明，开减振孔锯片可有效降低圆锯片的振动，为圆锯片降低振动的结构设计及基体冲孔的优化设计提供理论指导。

Abstract

Saw blade is a thin plank with a large area. During the high-speed sawing, the vibration of the saw is a universal phenomenon. In order to improve its sawing performance and reduce its working vibration, on the basis of vibration analysis of circular saw and theoretical study of experimental modal, compares the inherent characteristics of two different structures of circular saws and analyses the changes of lts natural frequency and vibration mode, as well as concludes the effects of opening an damping hole which affect the overall performance, especially for the vibration. Experiment shows that opening an damping hole can reduce the vibration effectively. All these can provide theoretical guidance for the structure and optimal design to reduce the vibration of the circular saw blade.
