摘　　要：在ANAYS/LS-DYNA中建立了普通刀具和仿生刀具的有限元模型,并运用显示动力学分析程序ANSYS/LSDYNA对两种刀具切削土壤过程进行了数值模拟分析,得到了切削土壤的等效应力分布情况。结果表明,仿生刀具可以起到减小切削阻力的效果。In this paper, the finite element models of the general tools and bionic tools are established in ANAYS /LS-DY-NA, and the numerical simulation analysis on the cutting soil process of these two tools are also made by using the explicit dy-namics to analyze program ANSYS /LS-DYNA, and finally the equivalent stress distribution of cutting soil is obtained.The result shows that bionic tool can reduce the cutting resistance.

关 键 词：仿生刀具 有限元模型 切削阻力 动力学分析
