金属切削过程的有限元法仿真研究

根据材料变形的弹塑性理论,建立了材料的应变硬化模型,采用有限元仿真技术,利用有限元软件ABAQUS对中碳合金钢40CrNiMo切削过程中剪切层及切屑的形成进行仿真,分析切削加工区域的应力、应变的分布。该方法比一般的试验法更省时省力,在研究金属切削理论、材料切削性能及开发刀具产品方面有着工程应用价值。

Study of Metal Cutting Process Simulation by Finite Element Method

Based on the technology of elasticity and plasticity in material deformation,the strain-hardening material model and finite element model are established with FEM software ABAQUS,to simulate the formation of shearing layer and chip in medium-carbon alloy steel 40CrNiMo cutting process.The stress and the strain in the machining area are analyzed.The method is more effective and efficient than the traditional method of experimental engineering,and valuable in the study of metal cutting theory,material cutting performance and development tool products.
