在铸造工艺CAD中用微机实现凝固过程仿真的温度场三维显示技术

The Graphic-Method of Quick Display 3D Temperature Fied Using Microcomputer in Solidification Simulation of Casting Technological CAD

在CAD中,用微机生成三维图形要达到实用化程度,速度是关键因素。作者在PC/XT上实现的程序可以把大型铸件凝固过程仿真的结果以三维立体图形式显示,铸件的尺寸和角度可变,生成时间仅为数十秒。文本介绍作者所用的方案、算法及技巧,以及它们在研制通用的温度场仿真的后处理程序中的价值。

The key to practical using 3D graphic technique into GAD on microcomputers lies in the speed. The graphic program developed on PC/XT by the authors can quickly display 3D temperature field simulating solidification on a heavy cast of mill housing within 30 seconds. The paper presents the concept, methods and technics employed by the authors, and evaluate their values in dsveloping general-purpose post-processing program for temperature field simulation.
