| 摘 要： | 为导弹用隔热层的设计提供了一个理论模型.这个模型在隔热层材料的选择及厚度的优化上经常用到.导弹内隔热层采用了单隔热材料的结构.在做出一定的假设后, 问题可简化为一维非稳态导热.采用了有限差分法对导热微分方程进行求解, 并对热导率假设前后的计算结果进行比较.结果表明这种方法是合理的, 且大大简化了计算过程, 这为类似的工程计算提供了一种很好的计算方法.

| Abstract: | Theoretical model is presented for the insulation package of missile.This model can be used for characterizing insulation material and thickness optimization.The insulation package inside missile adopts the structure of a single insulation material.With some assumptions,the problem can be predigested to one-dimension unsteady state heat conduction.A finite difference technique is used to solve the equation,and the results are compared.The result indicates that this method,which makes the computing process simple,is reasonable and an effective approximate method for similar problems. |
