摘　　要：在已完成的焊接凝固裂纹数值模拟工作的基础上 ,作者设计了一个凝固裂纹数值模拟系统。文中主要介绍其中的温度场数值模拟后处理系统。该系统以ADINT软件为基础 ,利用VisualBasic6 .0作为主要编程语言 ,借助数学软件MATLAB5 .3及MatrixVB矩阵运算函数库建立了温度场数值模拟后处理系统 ,实现了温度场的三维、等高线、横截面、纵截面和循环线的显示功能。通过方便的位置和时间步设置 。On the basis of the previous study on welding solidification crack,the paper has developed a system for simulating welding solidification cracks.In the paper,the post treating module of the system,namely simulating results of temperature field,is introduced.Based on a commercial finite element calculating software package,ADINT,the module uses program language Visual Basic 6.0 as main language to develop a data treatment system by combining with the math software package,MATLAB5.3,and matrix calculating function,Matrix VB.Providing a simple way to set up the position and time step to be treated,the module can display calculated temperature results in any positions and at any time steps.Temperature fields can be shown in the forms of three dimensions,contours and feature curves in transversal and vertical section,and the thermal cycles can be calculated and displayed in a given point.
