摘　　要：利用CAE软件对轴承座铸件的原方案凝固过程进行数值模拟,模拟结果预测铸件内部容易产生缩孔缩松缺陷,这一情况和实际生产相符。在不改变原有浇注系统的前提下,改变铸件结构,对新的工艺方案进行凝固过程数值模拟,模拟结果表明新的工艺方案可有效地避免铸件缺陷的产生,提高铸件质量。通过实际生产验证,确定改进工艺方案切实可行,铸件质量满足客户要求。The original casting process for bearing block casting was simulated by InteCAST software.The simulated results predicted that there are slag inclusion and porosity shrinkage defects in casting. The casting structure was modified and simulated. The new simulated results show that the defects are removed. The casting which can Ineet the customer requirements is successfully produced using the new process.
