摘　　要：采用有限元仿真分析方法,利用有限元增量理论建立了玻璃材料的弹塑性本构关系,对单颗金刚石磨粒的磨削过程进行了仿真,最后从最大拉应力、磨削力、磨削力比3个方面对仿真结果进行了分析研究,为玻璃磨削加工的工艺参数优化和工艺规划奠定了基础。In this paper, elastic-plastic constitutive relation of glass was established by the use of finite element incremental theory, and the single-grit diamond grinding process was simulated. The simulation results were analyzed from the aspects of the maximum tensile stress, grinding force and grinding force which laid a foundation for process parameters optimization and process planning for glass.
