Overview

Simulation demonstrates reduced shrinkage porosity in ductile iron flywheel casting, indicating improved microstructure control.

Key Points

  • The aim is to optimize casting parameters and control microstructure in flywheel manufacturing.
  • Integrated macro-micro-simulation using finite element and cellular automaton approaches
  • Orthogonal testing for optimal casting parameters
  • Simulation of solidification and microstructure based on determined parameters.
  • Shrinkage porosity volume reduced from 4.043 cm3 to 0.808 cm3 with optimal parameters
  • Defect rate decreased by 79.9%
  • Surface nucleation parameter had negligible influence, while bulk nucleation parameters significantly affected microstructure.
