基于节点群整合方法的航天器热网络模型修正技术

根据航天器节点热网络方程的组成，结合实际机构的工程特点，建立了节点群参数化热网络整合方程，提出以此为基础的航天器热网络模型修正技术.基于原型热试验数据和导热基本原理的温度外推计算公式，可用来确定无测点的节点温度，解决航天器热试验温度测点不足，致模型修正工作无法付诸实施的难题.利用热网络修正模型，可以得到误差在工程许可范围的计算结果.

Correction Technique of Spacecraft Thermal Network Model on the basis of Node Group Combined Method

On the basis of the component of node thermal network equation in spacecraft and combining design feature of actual mechanism,a parametric node group thermal network combined equation whose physical meaning is definite was established and the correction technique of thermal network model for spacecraft was made on this basis.The extrapolated formula for calculating temperature that is based upon hot tests and basic principle of heat transfer can be used for determining those node temperature on which there ...
