| 摘 要： | 对二维圆环内孔磨削的温度场和应力应变场用有限元方法进行了仿真.用命令流方式建立了圆环传热有限元分析模型,采用外圆夹紧与盘面夹紧方式进行了对比,计算得到工件的温度场基本上呈环状分布,周向基本均匀,径向温度梯度较大；内孔最大热变形出现在夹紧位置之间,达到了0.030mm,外圆最大热变形达到0.062mm,内孔磨削后将产生较...

| Abstract: | The temperature field and stress-strain field are simulated for an internal ground cirque.Finite element models of surface locating and three-jaw chuck clamping have been considered and compared.Computation shows that the temperature in circumference is basically uniform,but radial temperature grad is big.The maximal thermal deformation in ground hole is found in clamping positions,and reaches 0.030mm.In outer circle the maximal thermal deformation reaches 0.062mm.After ground,the inner hole will form sizea... |
