| 摘 要： | 本文利用三维制图软件对铸件进行三维造型、在将实体离散为有限差分网格单元的基础上,辅之以一定的边界条件和热物性参数库,进行三维传热计算,最后根据一定的判据,定量地预测铸件缩孔缩松等缺陷产生的部位和大小.通过优化铸造工艺来消除和避免缺陷的产生,以达到确保铸件内部质量,获得显著经济效益的目的.

| Abstract: | On the basis of three-dimension casting modeling by using three-dimension drawing software to calculate three-dimension heat-conduction, according to certain criterion, the size and position of defects such as holes and rarefaction in casting can be predicted. The defects can be eliminated and avoided by optimization casting technology, so as to guarantee the internal quality of casting and obtain the purpose of prominent economic benefits. |
