摘要
本文在[1]的静力简化分析的基础上,讨论了筒中筒结构弯扭耦联的动力特性问题。计算了前九个自振频率和振型,并引出了相应的结论。
In this paper, based on the static simplified analysis, Ref. [1], the dynamic characteristic of combination of bending and torsion for tube-in-tube structures is discussed. The first 9 frepuencies and the corresponding vibrant modes are givn. Finally some conclusions are introduced.
