本文在等效液面收缩法和孤立域法基础上建立了预测铸钢件缩孔的新方法———多热节和即缩即补方法 ,该法实现了对模拟铸件各热节的内部动态瞬时补缩 ,并采用该方法对两个实际铸钢件进行了缩孔分析。 In this paper, the equivalent liquid surface shrinkage method and isolated domain method based on the establishment of a prediction of shrinkage of steel castings new method - that is, the Ministry of hot and short Shouchu method to achieve the simulation of the hot section of the internal casting Dynamic instantaneous shrinkage, and the use of the method of two actual steel castings were shrinkage analysis.
