卫星虚拟热试验平台建模工具模块研究

Tool module for modelling satellite virtual thermal test platform

为预示卫星热试验结果,给热试验设计提供参考,北京卫星环境工程研究所自主研发了卫星虚拟热试验平台。文章介绍了虚拟热试验平台中建模工具模块的建模思想、对象组合策略和数据存储方法;其中数据存储方法采用预排序遍历树算法,相比于传统的邻接列表模式,具有更高的查询效率;最后还介绍了基于本建模工具模块的红外加热笼建模方法。

The virtual thermal test platform is developed to predict the results of a real thermal test,and therefore it can be used to design the real thermal test.The modeling method,the object combination strategy,and the data storage scheme of the modeling tool module for the virtual thermal test platform are analyzed.The model data are stored in the datasheet and queried by using a modified preordered tree traversal algorithm.This algorithm is more efficient,as compared to the adjacency list model.Finally,a method of modeling the infrared cage based on the modeling tool module is presented.
