  • Industrial Applications of Computer Simulation System to Sand Mold Castings

抄録

  Computer simulation of solidification of casting has been newly developed and successfully applied industrially. Forward finite difference method was used for the analysis of two-dimensional and three-dimensional radial symmetric heat transfer in sand mold casting. As for the analysis of complicated shapes, a two-dimensional converting method based on Chvorinov’s rule was newly proposed. Data input in this numerical simulation is interactively performed by the computer graphics system consisting of a tablet/digitizer and a graphic display, and the result is graphically output in three forms : temperature distribution, solidification time and time-temperature plot. The simulation result was compared with that which was experimentally obtained in iron castings and a satisfactory coincidence was obtained for demonstrating the capability of predicting solidification process and shrinkage defect.
