Abstract：For This paper introduces a kind of casting process for heavy duty truck casting beam, which is made of green sand by high pressure molding line , making core with coated sand.The casting is thin-walled shell castings. There are several local isolated hot spots in the mounting part of the frame and the assembly connection part of the V-shaped stinger, and the risk of porosity and shrinkage cavity is high. Using MAGMA software for filling and feeding of casting process, based on the filling temperature field, the particle tracking simulation to determine the existing risk of defects such as porosity, cold shut, slag inclusion, through the analysis of the fraction liquid and shrinkage criterion to judge the risk probability of causing shrinkage defects , integrated simulation result of filling and solidification process, optimize the original design and trial-manufacture model, finally obtained the qualified castings.
