摘　　要：利用ANSYS/LS-DYNA软件建立绞刀和土体的有限元模型,应用LS_DYNA的显式动力学分析算法,对绞刀切削土壤的动力学过程进行模拟,得到绞刀在切削土体时功率消耗、切削阻力以及土壤的等效应力变化规律,为绞刀-土壤切削研究提供一种新的手段和方法。Using the software ANSYS/LS-DYNA to establish the cutter and soil finite element models.Using LS-DYNAexplicit dynamic analysis algorithm to simulate the dynamic process of the cutter-soil cutting,we obtained the power consumption,cutting resistance and change rule of the equivalent stress when the cutter was cutting soil.This paper has provided a new meanand method for the cutter-soil cutting research.
