摘　　要：利用有限元分析软件ABAQUS建立了车削40Cr Ni Mo的有限元模型,并在不同切削用量条件下对切削力进行仿真,得到了主切削力、进给力的变化规律,分析了引起切削力变化的主要原因。结果表明:切削分力中主切削力最大;切削深度对切削力尤其是主切削力的影响最大,进给量次之,切削速度的影响最弱。A finite element model for turning 40 CrNiMo steel is established by using ABAQUS software,which is used to simulate the cutting force with different cutting parameters,the variation range of the main cutting force and feeding force are obtained in the simulation,at last the main reasons for the variation of cutting force are analyzed. The results indicate that the cutting force increases linearly with the cutting feed and the cutting depth,the cutting depth has a greater impact on the cutting force than cutting feed,the cutting speed has smallest effect to the cutting force.
