The invention belongs to the technical field of ship design, and particularly discloses a flexible structure for a cross point of a ship bulkhead, which comprises any three cross rigid plates, the centralized intersection point of the three rigid plates is marked as the cross point, and at least one rigid plate close to the cross point is provided with a groove profile; the groove-shaped design is adopted, so that the longitudinal bulkhead becomes a flexible structure near the intersection point, the stress distribution is more uniform, and the phenomenon of stress concentration is effectively reduced; when being impacted or vibrated, the energy can be better absorbed and dispersed, the problems of fatigue damage, crack propagation and the like are not prone to occurring in the long-term use process, and the safety of the ship structure is improved.
本发明属于船舶设计技术领域,具体公开了一种用于船舶舱壁十字交叉点的柔性结构,包括任意三个十字交叉的刚性板,三个刚性板集中相交的点标记为十字交叉点,在至少一刚性板靠近十字交叉点处设置一槽型;本发明采用槽型设计,使得纵舱壁在交叉点附近变成了柔性结构,使得应力分布更加均匀,从而有效减少了应力集中的现象;在受到冲击或振动时,能够更好地吸收和分散能量,在长期使用过程中不易出现疲劳破坏和裂纹扩展等问题,提高船舶结构安全性。
