摘　　要：以铝合金轮毂低压铸造充型过程为研究对象,在原有的SOLA-VOF算法基础上提出了内外区域分离简化算法,设计程序模拟了该铸件的充型过程。结果表明,内外区域分离简化算法具有运行时间短、计算效率高等优势,得到了与SOLA-VOF算法基本相同的模拟结果。Taking filling process of aluminum alloy wheel in low pressure casting process as research object, a simplified separation algorithm of the inner and outer regions was proposed based on the original SOLA-VOF algorithm, and the filling process of the casting was simulated using the designed programme. The results show that the simplified separation algorithm of the inner and outer regions has the advantages of short running time and higher calculation efficiency; the simulation results are basically the same as the SOLA-VOF algorithm.
