Applicability of MPH Method to Die Casting Processes

Abstract

  Since die casting simulations need to calculate complex multi-physics simulations, such as the interaction between solid and the flow of molten metal, a calculation method which can handle a wide range of calculation conditions is required. The MPH (Moving Particle Hydrodynamics) method, which is a particle method based on analytical mechanics, may be effective for the die casting simulations as it has high numerical stability. In this paper, the applicability of the MPH method to the die casting simulation was investigated. The fundamental models of heat transfer, phase change, and variable volume were introduced to the MPH method, and the calculations which simulate the die casting process with simple geometries were conducted. It was shown that the proposed method has the potential to simulate various phenomena in the die casting process in a unified manner.
