以ZTC4合金框形铸件为对象,用Solidworks建模,用Meshcast软件进行网格剖分,解决了三维模型与网格分析软件之间的接口问题。采用Pro-cast软件分析了铸件充型过程中液体流动及温度场分布规律,预测了铸件中缩孔、铁豆易出现的位置,预测结果与铸件实际情况相吻合。将分析结论应用于同类型更大更复杂的框形铸件的工艺优化中,避免了同类缺陷的发生。 ZTC4 alloy frame castings as the object, with Solidworks modeling, Meshcast meshing software to solve the problem of the interface between the three-dimensional model and the grid analysis software. Pro-cast software was used to analyze the distribution of liquid flow and temperature field in the process of casting filling. Predicting the location of shrinkage cavities and iron beans in castings, the predicted results are consistent with the actual situation of castings. The conclusions of the application of the same type of larger and more complex frame casting process optimization, to avoid the occurrence of similar defects.
