| 摘 要： | 一致缺陷模态法是网壳结构缺陷稳定分析中的一种重要方法,但是根据本文的分析,该法直接应用于组合空间结构却存在一些问题.为了充分发挥一致缺陷模态法的优点,文章提出了具体的改进方法.并讨论了利用改进方法得到的最不利几何缺陷对结构自振频率的影响,得到了一些对组合空间结构设计有益的结论.

| Abstract: | The consistent imperfect buckling analysis method is used frequently in the imperfect stability anal-ysis of the reticulated structure,but according to the analysis of this paper,the method is not suit for the com-bined space structure system.So it is improved to be able to analyze the combined space structure system.The improved consistent imperfect buckling analysis method is approved correct by finite-element methed.And the influences of the geometry imperfection on the natural frequencies is discussed b... |
