摘要
介绍了土壤切削和有限元法的基本概念,探讨了国内外学者使用有限元法模拟土壤切削过程的进展情况,总结了有限元法在土壤切削过程模拟中遇到的问题。同时,提出了应加强对有限元法在多参数交互、有秸秆混合的复杂土壤条件下的切削过程模拟的研究。
In this paper, the basic concepts of soil cutting and the finite element method is introduced. The domestic and aboard research progress of the finite element analysis of soil cutting is reviewed. The problems existing in the application of finite element are pointed out. The research in finite element method should be strengthened in the simulation of the soil cutting process, such as the interactive multi -parameter, straw mixed soil cutting process in complex conditions etc.
