摘　　要：针对高弹性合金钢3J33的难加工性与实验复杂性问题,在其加工过程中进行了仿真模拟的研究。基于弹塑性力学、磨削加工机理和有限元分析等理论,利用专业金属切削仿真软件AdvantEdge,构建了考虑硬度的单颗磨粒磨削细筋的残余应力仿真模型,对不同硬度下磨削时的细筋残余应力进行了仿真分析和对比,并通过实验加以论证,最终验证了优化后的仿真模型具有可靠性。Aiming at the problems of machining difficulty and experimental complexity of highelastic alloy steel 3J33,a simulation study was carried out in the machining processes.Based on the elastic-plastic mechanics,grinding mechanism and finite element analysis,considering hardness for single grain grinding thin rib a residual stress simulation model was established by professional metal cutting simulation software AdvantEdge.Simulation analyses and comparisons of the residual stresses of different hardnesses for thin ribs were conducted when grinding and verified through the experiments.Finally,the reliability of the optimized simulation model was verified.
