The modal neural files ( mnf ) derived from i - deas modal solution were imported into the adams / flex. then the flexible multi body dynamics simulations of the deployable truss system were carried on when the truss is assembled with a spacecraft. the dynamics characteristics of the truss in the moment of folded state and completely deployed state were listed
利用i - deas對桁架單元的模態進行計算，生成模態中性文件，然後將其輸入到adams / flex里與衛星組成柔性空間展開桁架結構模型，進行展開桁架的多柔體動力學模擬計算。 -
Manifold, as the main theme of differential geometry and analysissitus, has a basic structure composed of finite cover system and contact functions between covers, which could be overlapped or even folded
與通常的網格不同，覆蓋可重疊或折疊產生一個組合空間，因此流形方法是追求一切空間上的所有解法。 -
This thesis is a fem analysis of opening process of the folded horizontal tail wing of some aircraft, and the work includes modeling the detailed mechanic assembly of the tail wing, and computing its elastic dynamic process by large - scale fem software system, ansys and ls - dyna3d, as well with the postprocessor tool - lspost to take the computational results into visualization
本文運用大型有限元cae軟體ansys和ls - dyna3d對某具體飛行器水平折疊尾翼的機構運動進行了細致的有限元建模和動力學計算分析，運用lspost對計算結果進行了詳細的后處理，運用可視化技術對數值分析結果進行了圖形及曲線描述。
