摘要
Abstract
With the development of spacecraft technology,the size and complexity of spacecraft structure system increase remarkably.In order to realize high efficience in structual analysis for such complex systems and protect know-how in FE model transfer between different organizations,a substrucure analysis method based on MSC.NASTRAN software is presented with the examples of spacecraft structure anlysis.Enigineering applications indcate that this method plays an important role in shielding design parameters of structures in model transformation and improving analysis efficiency of compliacte spacecraft system.关键词
