The research presented in this paper aimed to change the existing gating system that would enable the engine body casting, from a new EV31A magnesium alloy, of the required quality. For this reason, the casting process simulations used the MAGMASoft software, followed by the experimental validation of the achieved results. The results achieved in the first stage of the cast computer simulation enabled the identification of potential problems and factors that reduce the casting quality. However, the proposed design modifications eliminated the inadequate delivery of liquid metal to the casting's critical areas by adequately controlling the mold cavity filling and solidification process. The experiment validated the simulations of the computer casting defects at the various stages. The results enabled the new EV31A magnesium alloy to be implemented in industrial production.
本文所展示的研究旨在改变现有的浇铸系统，该系统要能够浇铸出符合质量要求的新型EV31A镁合金发动机缸体铸件。因此，铸造过程模拟使用了MAGMASoft软件，随后对所得结果进行了实验验证。在铸件计算机模拟的第一阶段所取得的结果，使得识别出降低铸件质量的潜在问题和因素成为可能。然而，所提出的设计改进措施通过充分控制型腔填充和凝固过程，消除了液态金属向铸件关键区域供应不足的问题。实验验证了铸件在各个阶段计算机模拟出的缺陷。这些结果使得新型EV31A镁合金能够应用于工业生产。
