摘　　要：为了降低金刚石圆锯片锯切噪声,提出一种适用于多约束条件下的圆锯片减振降噪动态拓扑优化设计方法。基于混合元胞自动机算法构建了低噪声圆锯片动态拓扑优化模型,以锯片减振降噪为设计目标,以锯切过程的锯切力、位移载荷响应为多约束条件,对优化模型进行计算分析,得到了满足刚度要求的最优开槽圆锯片,降低噪声5.1 dB。依据优化结果制备了开槽锯片,通过锯切实验,验证了优化结果的正确性。该方法为低噪声圆锯片的动态拓扑优化设计提供了新思路。In order to reduce the sawing noise of diamond circular saw blades,a dynamic topological optimization design method for circular saw blades under muti-constraint conditions was proposed. Based on the hybrid cellular automata algorithm,the dynamic topological optimization model of a slotted circular saw was established,which takes the vibration and noise reduction of the saw blade as the design goal,and the load response and displacement response as muti constraints at given positions. By solving and analyzing the optimal model,the optimum form of the saw blade with the required rigidity was obtained. The noise is reduced by 5.1 dB.According to the optimization results,the slotted circular saw blade was prepared,and the correctness of the optimization results was verified by sawing experiments. The results provide a reference to the dynamic topology optimization design of low noise circular saw blades.
