I-DEAS软件在单相流体回路辐射器热分析中的应用

A Study on the Use of I-DEAS in Thermal Analysis of Fluid-loop Radiator

以神舟飞船单相流体回路辐射器为例,介绍了采用I-DEAS软件进行辐射器热分析研究的方法,包括建模、划分网格、计算及后处理等,并将仿真分析结果与热试验结果进行了对比。结果表明:采用I-DEAS软件对单相流体回路辐射器热分析具有很好的实用性和计算精度,显著降低了辐射器热分析的难度,并在一定程度上简化了前期设计中热试验验证的需求。

Setting Shenzhou spaceship＇s single phase fluid-loop radiator （SPFLR） as an example, this paper introduced the method of using I-DEAS software to make thermal analysis and design of radiator, including modeling, meshing, calculation, post processing and so on. Through contrasting I-DEAS software results with the results of vacuum tests, the result shows that using I- DEAS software to do radiator research is universal, practical and precise, which could make SP- FLR research easier or even simplify some real tests in the SPFLR design.
