Numerical Simulation of Die Casting Process for Motor Housing and Prediction of Thick Wall Defects
Aiming at the complex casting process of the electric power steering motor shell and the high quality require-ments,the finite element model was established by the HyperMesh and ProCAST software,the casting process of the electric power steering motor shell was carried out and the location and size of defects inside the castings were pre-dicted.Trial-production was conducted based on the optimized process schme,and X-ray flaw detection observation was carried out for castings.The experimental results indicate that the defect prediction results are consistent with the actual casting,and shrinkage porosity and cavities appear on the lugs and thick walls on both sides of the housing.
