| Abstract: | A combined FDM/FEM software system was developed to analyze the temperature and stress distributions in castings. The FDM was used to calCulate the temperature distribution while the FEM was used for the stresssimulation. For practical application, a machine tool bed iron casting was selected and the high temperature mechanical properties of the cast iron were measured. The FDM/FEM simulation results of the temperature and stressdistributions of the solidification process of the casting using current production technology agreed well with the measured temperature and residual stress results. A modified production technology was then proposed. The numericalsimulation results showed that the temperature distribution of the modified production technology was more uniformand the distribution and value of residual stresses were more favorable to dimensional stability of the machine tool. |
