衛(wèi)星虛擬熱試驗平臺建模工具模塊研究

Tool module for modelling satellite virtual thermal test platform

摘要: 為預(yù)示衛(wèi)星熱試驗結(jié)果，給熱試驗設(shè)計提供參考，北京衛(wèi)星環(huán)境工程研究所自主研發(fā)了衛(wèi)星虛擬熱試驗平臺。文章介紹了虛擬熱試驗平臺中建模工具模塊的建模思想、對象組合策略和數(shù)據(jù)存儲方法；其中數(shù)據(jù)存儲方法采用預(yù)排序遍歷樹算法，相比于傳統(tǒng)的鄰接列表模式，具有更高的查詢效率；最后還介紹了基于本建模工具模塊的紅外加熱籠建模方法。

Abstract: 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.
