Abstract

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.
