　　摘要 本文建立了多孔基体与非等弧长节块相组合的特殊结构金刚石圆锯片瞬态动力学模型，通过ANSYS软件对特殊结构金刚石圆锯片的有限元模型进行瞬态载荷响应计算，得出不同切削参数对锯片关键部位瞬态应力和变形的影响。分析结果表明，进给速度对锯片应力和变形影响最大，切削速度次之，切削深度最小。特殊结构金刚石圆锯片在变形、应力方面与普通结构金刚石圆锯片相比，都得到了较大改善。此分析对实际工程应用及进一步优化锯片结构具有一定的指导意义。(金刚石与磨料磨具工程2009年第四期)
　　
　　Abstract A transient dynamic model of diamond circular saw blade with multi-holes core and different width segment was built in this work． Based on ANSYS software，the transient response of saw blade was calculated,and effects of different cutting parameters on the transient stress and deformation of saw blade, s key positions were found．The analysis results indicated that the chief influence factor of transient response is feed rate．the cutting speed takes the second place，and the depth of cut is the last. Compared with the conventional struc-tured saw blade，the special structured saw blade showed improvements in stress and deformation．The analysis has some guiding significance for actual application and further optimization of saw blade structure．
