摘　　要：为了探索氧化锆陶瓷材料磨削中磨削工艺参数对磨削表面残余应力的影响,设计了正交实验,研究了磨削深度、砂轮线速度和工件进给速度等磨削工艺参数对磨削表面残余应力的影响。同时,引入JH-2本构模型,以ABAQUS为基础建立单颗金刚石磨粒切割氧化锆陶瓷有限元仿真模型,并将实验结果与模拟结果进行对比。结果表明,随着砂轮转速和磨削深度的增加,磨削表面的残余应力值先增大后减小。试验结果与仿真输出结果基本一致,验证了该仿真模型的正确性。Due to the exploration of the influence of zirconium porcelain grinding process parameters on the residual stress on the cutting surface,the orthogonal test was designed,and the grinding number on grinding and stress such as grinding depth,grinding wheel line speed and working feed rate were studied.In the same era,the constitutive model of the liquor was introduced,and a single diamond grinding mold model was established based on the fish,and the results of the actual verification were compared with the simulation speculation.It has its end,and its use is also.The test results are basically consistent with the results of the simulation output,and the correctness of all the mold models is verified.
