| 摘 要： | 采用Pro/E软件为前处理平台,以ProCAST软件为模拟平台,对涡壳件充型及凝固过程进行了模拟仿真.通过预测产生收缩缺陷的敏感区域,对涡轮增压器壳体(涡壳)的铸造工艺进行了分析与评价.结果表明,铸件在充型初期存在一定程度的紊流,但充型速度较低,产生裹气、夹渣等缺陷的可能性较小；缩孔缩松敏感区主要分布于几何热节处和流道法兰根部等处,而以涡壳底部与流道相贯的几何热节处最为敏感,但与单内浇道引入工艺相比,双内浇口引入工艺产生缩孔缩松缺陷的可能性明显减小. |

| Abstract: | Analog simulation was conducted on the filling and solidification of turbocharger shell by using Pro/E software as the pre-treatment platform and using ProCAST software as the simulation platform.The foundry technology of turbocharger shell was analyzed and evaluated by predicting the sensitive area of shrinkage defects.The results show that,turbulence exists in the primary stage of filling mould,but due to the lower rate of filling,the possibility of wraped gas and slag inclusions is reduced;the sensitive ... |
