宇航电子设备中壳体的有限元分析

Finite Element Analysis for Shell of Electron Equipment of Astronavigation

就宇航电子设备中壳体结构的建模进行了研究，采用板壳单元来描述结构，用局部刚化模拟壳体转角和加强处，并对壳体单元自由度和复杂边界条件的处理作了大胆有益的探索。

The thesis describes the Iesearchs that the author has done on modelling for shell of electron equipment of astronavigation, In this thesis, shell elements are used to imitate the structure, a method called Part Stiffeness is utilized to simulate the corner and the reinforced place. Moreover, the author has gone further into profitable exploration on dealing with the structure's element freedoms and it's compli-cated boundary conditions.
