摘　　要：简要介绍充型凝固过程数值模拟的实际意义,分析了充型凝固过程数值模拟的特点,利用建立的数学模型对YL112铝合金压铸件进行了模拟。通过对模拟结果的分析,预测了铸件在充型凝固过程中可能形成的缺陷,基本上与实际相符,并对现行的工艺方案提出了一些改进措施。The numerical simulations of mold filling and solidification process for the YL112 aluminum alloy were done by the supposed mathematical model.The casting defects in the process of mold filling and solidification were predicted by the result of the casting simulation. The casting defects of simulation are well compared with the practice.Some measures presented were improved for the existing technological process.
