基于数值模拟的温场测试技术研究

通过在环境温度试验箱的某些位置布置适当的节点,对采集回来试验箱内的温度等实际数据,在对试验箱的空间建模的基础上,采用插值法和适当次数的拟合函数的拟合,用一个无限细化的三维矩阵来模拟出试验箱内的温度分布情况,得出三维矩阵的实际值的分布,最后结合MATLAB软件绘制出计算出的温度场的三维图像,从而可以直观具体地了解环境温度试验箱的温度场分布情况。本文仅对于形状规则的长方体试验箱进行数值模拟,对其特殊截面的温度场进行详细的分析。

Study on Temperature Field Test based on the Numerical Simulation

In this paper we get the three dimensions distribution map of the temperature field for the test chamber which can directly and expediently understand the specific distribution of the temperature field of environment test chamber,through in arranging some appropriate testing point in the environment temperature test chamber ,using interpolation and appropriate function fitting method and an infinite detailed three-dimensional matrix to simulate the temperature distribution of the test chamber based on the actual data collected of the testing point.This simulation and analysis only aimed at special section of the rectangle test chamber.
