- Abstract : by mean of adjusting the position and shaps of risers , shrinkages and porositi es in balancing axle case are eliminated on the principle of direirional solidification , its density is a lso improved
文摘:根据动态顺序凝固的原则，对斯太尔平衡轴壳铸钢件设计合理的冒口位置和形状；有效地消除了铸件热节部位的缩孔，提高铸件的致密度。 - Abstract : the relation between the place ， size ， shape and number of hot spots in casting and the changes of factors such as geometry factor ， physics factor ， technics factor in the casting and mould system and the systematic characteristic of hot spot are studied by means of the technique of computer numerical simulation of solidification . the relationship between riser and hot spot is also discussed in this paper
文摘:采用计算机凝固数值模拟技术，研究铸件热节的位置、大小、形状和数量，在凝固过程中根据铸件?铸型系统内几何因素、物理因素、工艺因素等各因素的变化关系，揭示热节的系统性；讨论了冒口与热节的位置关系。 - Abstract : based on equivalent liquid surface descending method ( elsdm ) and isolated melting zone method , a multi - hot - spot and simultaneous shrinkage - feeding method was established to predict the shrinkage cavities of steel casting during solidification simulation . the shrinkage in each hot spot can be simulated and fed dynamically and simultaneously by itself using this method . then two practical steel castings were analyzed by this method
文摘: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。
