Abstract：Based on the combination of sequential response surface model and hybrid optimization algorithm, an optimization method to reduce the sawing noise of diamond circular saw blade under complex load is proposed. In this paper, a mathematical model for the structural optimization of diamond circular saw blade under multi-variable and multi-constraint conditions was established, and the optimized circular saw blade which meets the requirement of stiffness was obtained by calculation. Through mathematical statistical analysis, the effects of size parameters on the acoustics, deformation and stress of the saw blade were obtained. According to the results, the diamond circular saw blade was prepared.The sawing experiments show that the optimized saw blade can effectively reduce noise, which shows that this method can be reference for the acoustic optimization of saw blade or such matter.
