    Abstract
  • To solve the resonance and the noise problems of diamond circular saw blades during operation, the workbench software was used to analyze the traveling wave resonance and the static force of the idling circular saw blade with the diameter of 600 mm, and the effects of openings and interlayers in the circular saw blade matrix on its traveling wave resonance were studied. The results show that the reasonable openings in the matrix of circular saw blade can avoid traveling wave resonance, and the circular saw blade with raindrop holes has the best vibration reduction effect, the maximum value of δ is 4.36%, which is much larger than 0.09% and 0.91% of non-perforated and circular streamlined holes. The interlayer of circular saw blade with raindrop holes is further optimized, its δ value is 7.58%, which is nearly twice that before the interlayer, and it is not easy to cause traveling wave resonance. At the same time, the deformation and stress of the optimized circular saw blade become larger, but far less than its allowable stress value, indicating that its strength and stiffness meet the service requirements and will not cause fatigue failure.
