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。
In order to indicate the result of satellite thermal test and provide references for thermal experiment design, Beijing Satellite Environmental Engineering Research Institute independently developed satellite virtual thermal test platform. In this paper, the modeling idea, object combination strategy and data storage method of modeling tool module in virtual thermal test platform are introduced. The data storage method adopts pre-sorted traversal tree algorithm, which has higher query compared with the traditional adjacency list mode Efficiency. Finally, an infrared heating cage modeling method based on this modeling tool module is also introduced.
