Abstract

SPH（smoothed particle hydrodynamics） method was used to simulate the filling process of vertical centrifugal casting. The three-dimensional mathematical model based on SPH vertical centrifugal casting filling process was established and calculated by hydraulics. The feasibility of the model was verified by using the mathematical model established. The actual casting filling process was simulated and compared with the ProCAST simulation ones. The practicality of the mathematical model and development program established was further explained.
