| 中文摘要: |
| 针对镁合金发动机缸体的结构特点设计了浇注系统,并用铸造分析软件对其充型和凝固过程进行了模拟。 通过观察分析模拟结果,预测了充型时间、凝固时间以及铸件中可能存在的缩孔缩松缺陷的分布与尺寸,并设计了优化浇注系统。 |
| 英文摘要: |
| Gating systems are designed for die casting of magnesium engine cylinder body by its structure characteristics. The filling and solidifying processes are simulated with finite element software. According to simulation results filling time, solidification time and the distribution and size of shrinkage porosity that may exist in the casting are forecasted. The optimization design of gating system is conducted. |
