摘要
出于总布置分舱和防火的需要,纵向轻围壁较为普遍地出现在各类船舶中。文中针对一全船有限元总强度分析中的纵向轻围壁的稳定性设计问题进行讨论,运用后屈曲理论分析其屈曲后的承载能力,并结合微分法分析其屈曲后对总纵强度的影响。提出了纵向轻围壁屈曲后的设计思想,可为纵向轻围壁的优化设计提供参考。
Longitudinal partition bulkhead has commonly appeared in kinds of ships due to demands of arrangement and fireproofing. Discussion has been conducted about the stability of the longitudinal partition bulkhead in global longitudinal strength calculation of a ship by FEM model. Load capacity after buckling is analyzed using post buckling theory and differentiation method is also adopted to study the effects. A design concept of the longitudinal partition bulkhead after buckling is put forward,which can provide reference for optimization of the structure.
