摘要
本文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随凝固时间的变化规律,揭示热节的动态性。
This paper uses the technique of computer numerical simulation of solidiEication,discuss- es the changes of position,size,shape and number of casting hot spot with the time in the course of solidification,and reveals the dynamic characteristic of hot spot.
