摘　　要：采用有限元分析软件Deform 3D建立了适合高速磨削仿真的Johnson-Cook材料本构模型,构建了反映金属磨削过程高温、大应变及高应变率状态的切削模型,模拟了40Cr钢磨削加工过程,对磨削弧区温度场、热流以及温度变化的仿真结果进行了分析,验证了有限元模型的合理性,为实现对工艺参数的优化选择奠定了理论基础。In this paper, finite element analysis software Deform 3D was employed to create the Johnson-Cook material constitutive model for high -speed grinding simulation, cutting model was constructed to reflect the high temperature, large strain and high strain rate state in the process of metal grinding to simulate the process of grinding 40Cr steel, as well as grinding arc temperature field, heat flowand temperature changes in the simulation results are analyzed to verify whether the finite element model is reasonable, and laid a theoretical basis for the realization of the optimization of process parameters.
