摘　　要：为提高金刚石圆锯片的锯切性能,降低其工作时的振动,防止锯片共振,通过锤击振动试验法,分析锯片固有频率的概率特性。依据结构固有频率与激振频率差的绝对值不超过规定值的关系准则,定义了锯片振动问题的可靠性模式和可靠度,提出避免锯片共振的频率可靠性分析方法。并通过对不同转速下的锯片可靠度的分析,得到了防止共振的工作转速,提高了金刚石圆锯片的使用寿命。The natural frequencies of the saw blade are obtained by using the hammer vibration test method in order to improve the cutting performance of diamond circular saw blade,reduce its working vibration,and avoid the saw blade resonance.With the criterion that the absolute value of the difference between the natural frequency and forcing frequency,the reliability mode and the reliability of saw blade vibration problem are defined,and the frequency reliability analysis method is put forwarded to avoid saw blade resonance.The life of the diamond saw blade can be extended through the analysis of the reliability of the different speed of the saw blade when it works in the best speed avoiding resonance.
