| Abstract: | The Phase change matrial(PCM) is intorced into the control technology of NC machine tool's thermal deformation. Based on the analsis of Phase change thermal conduction, the characteristics of two-dimensional heat transfer including the course of phase change are. studied.The variational formulation is derived.To employ the adaptive deforming grid finite element method, the temperature field and thermal deformation are successfully calculated and identified with the experimental meased results. |
