The Researcher And Implementation Of Computer Simulation Of The Gear Box Casting During Filling Process

The computer simulation for casting process is not only the cutting edge for the subject of casting technology development and the only way for improving traditional casting, but also the hot topics to all the expert in the world.Numerical simulation for casting process may optimize craft design, shorting trial cycle, cut the cost, decrease casting defect and assure the casting quality. Because of these advantages, it has been one of the hottest topic in the foundry world. Based on the theory of heat transfer, hydrodynamics and the theory of metal solidification, by using numerical analysis technology, database technology and visual technology, this paper provided a simulation and check method for the process design to simulate the fluent field and temperature field of the filling solidification and cooling, and can predict the casting quality according to these fields, thus, by this way, improved the quality of casting draft design. Adopting Pro/E 3D software and using the famous ProCAST software of American UFC company as simulation tool in the casting process, the interfaces has been deeply researched between the two software. By our research on the fluent field, temperature field and the prediction on the casting defect, we develop a new technical process for casting CAD/CAM.This paper example the casting gear box of the casting of mechanical department in the metal company and set a CAD model. By measuring actual working condition, we set up a material database for casting and sand mold, through choose reasonable model and parameters, we simulating the casting process successfully. The result of simulation is basically accord with the actual defect.
