摘　　要：本文建立了金刚石圆锯片的切削力分析模型,采用有限元的方法对金刚石圆锯片的水槽结构,以水槽的倾斜角度(水槽与径向之间的夹角)、水槽的底孔半径、水槽左、右侧边的角度结构参数为试验因素,进行静力分析计算,探讨各种结构参数对锯片最大Von Mises应力的影响。分析结果表明,在相同的工作条件下,合理的水槽结构能使锯片的应力分布均衡,高应力区均大大缩小,当水槽的倾角为γ=8,R=4.5,φ=ψ=5时,锯片的锯切效果最好,最大Von Mises应力降低13.87%,从而提高锯片的使用寿命。The cutting force analysis modal for diamond saw blade was established. The effect of the slope of the slots, radius of slot base circle, angle between the left slot side and the direction of the slot, angle between the right slot side and the direction of the slot were discussed. The largest Von Mises stress influences of various structural parameters were searched. An improved slot shape was suggested,which can make the saw blade stress distribution balanced, and the high stress area reduced. When the slot angle is γ = 8, R = 4.5, Ф = ψ = 5, the best cutting effect can be obtained, and the Von Mises stress can be decreased by 13.87 %, and thereby the fatigue life of the saw can be increased.
