为实现超薄型圆锯片曲线缝的结构设计，基于变密度法拓扑优化和模式搜索算法的形状优化相结合的方法，对圆锯片的曲线缝结构进行优化设计。通过基于变密度法的拓扑优化，确定曲线缝开设位置；以圆锯片整体振幅作为评价标准，以拓扑优化后得出的设计域作为边界条件，通过模式搜索算法对圆锯片曲线缝结构形状进行优化，得出给定约束和载荷条件下的最优解。在试验过程中进一步证明了曲线缝形状对锯片轴向振动影响的重要性。
To realize the curved groove structure design of the ultra-thin circular saw blade, the curved groove structure of the circular saw blade were optimized by combining topology optimization based on variable density method and shape optimization based on the pattern search algorithm. Using topological optimization based on the variable density method to determine the location of curved groove. The overall amplitude of the circular saw blade was taken as the evaluation criterion, the design domain derived from the topological optimization was taken as the boundary condition. The shape of the curved groove structure of the circular saw blade was optimized by the pattern search algorithm. The optimum solution of groove position, structure, and shape of circular saw blade was obtained under given constraints and loads. The importance of the shape of the curve slot on the axial vibration of the saw blade was further proved in the test.
