材料本构模型参数对二维直角切削仿真的影响
Influence of Material Constitutive Model Parameters on 2D Orthogonal Cutting Simulation
摘要
Abstract
2D orthogonal cutting simulation model has been built by commercial FEM code AdvantEdge.The influence of the governing parameters on the simulation results of 2D orthogonal cutting has been achieved by modifying the governing parameters of material constitutive mode,which includes the governing parameters of initial stress,strain hardening,strain rate hardening and thermal softening.It is found that the effect of gover-ning parameter of thermal softening on cutting forces,cutting temperature and tool stress is maximal,compa-ring the other governing parameters.The effect of governing parameter of initial stress on chip morphology is maximal,comparing the other governing parameters.Material constitutive model dominates the thermal-me-chanical coupling process in cutting simulation.The effects of constitutive model parameters on the simulated results show obvious nonlinear characteristics.关键词
