摘要

基于序列响应面模型和混合优化算法相结合的方式,提出一种在复杂载荷条件下降低金刚石圆锯片锯切噪声的优化方法。建立了多变量、多约束条件下金刚石圆锯片结构优化的数学模型,经计算得到了满足刚度要求的优化圆锯片。通过数学统计分析,获得了尺寸参数对锯片的声学、变形以及应力等性能影响规律。根据结果制备了金刚石圆锯片,锯切实验表明优化锯片能够有效的降低噪声,表明这种方法可为锯片或此类结构的声学优化研究提供新的方向和参考依据。

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.
