摘　　要：针对锈蚀金刚石圆锯片锯切时出现锯切稳定性降低的问题,根据不同锈蚀程度锯片的结构参数建立模型,采用有限元法对锈蚀锯片进行模态分析,将锯切振动作为稳定性的参考指标,研究锈蚀对锯片锯切稳定性的影响,并通过实验验证理论分析的准确性。结果表明:在640~1280 Hz频率范围内锈蚀锯片的振型模态比原锯片多6阶,并且相邻固有频率差值减小了8.56%,随锈蚀程度的增加,锯片更容易出现共振现象;锯片轴孔位置处和1/3至2/3半径圆环范围的锈蚀对锯片的锯切稳定性影响较大,因此可以通过优化加工参数、减少表面缺陷的方式减小锈蚀程度,降低对锯片锯切稳定性的影响。该研究为金刚石圆锯片的实际使用和防锈工艺提供了指导依据。When the rusted diamond circular saw blade works,there will be some problems such as reduced sawing stability.In response to this phenomenon,models are established through the structural parameters of saw blades with different corrosion degrees,and modal analysis of saw blades with different corrosion degrees is carried out.This analysis takes sawing vibration as a reference index of stability and studies the influence of saw blade corrosion on stability.Experiments verify the accuracy of the results.The results show that the vibration modes of the corroded saw blade more are more than 6 orders different from those of the original saw blade,and the difference in adjacent natural frequencies reduces by 8.56%in the frequency range of 640 to 1,280 Hz.With the increase of corrosion degree,the saw blade is more prone to resonance.Corrosion at the important position has a great influence on the sawing stability of the saw blade.Reducing surface defects can reduce corrosion and its influence on the sawing stability of the saw blade.This study provides guidance for the practical use and rust prevention technology of diamond circular saw blades.
