| 摘 要： | 双层舷侧内外壁板之间十字隔板相对刚度对船体舷侧结构的碰撞性能影响很大.通过对船舶碰撞动力学特性的分析,合理地简化了计算模型,并引入了相对刚度的概念,采用改变十字隔板厚度来改变结构相对刚度的办法,进行了系列仿真试验.结果发现,十字隔板相对刚度会限制舷侧结构变形损伤模式,以至于显著地影响到整个舷侧结构的损伤变形、碰撞力及能量的吸收与转换,尤其是最为关键的舷侧内板的损伤与之关系密切.通过合理地调整十字隔板的相对刚度,在一定程度上可以实现对舷侧结构碰撞性能的优化设计,为船舶舷侧耐撞性设计提供依据.

| Abstract: | Relative stiffness of the cross-frame located between the inner and outer shell of shipboard has a great impact on the crashworthiness of shipboard.Based on the analysis of dynamic behavior of ship collision,the computational model is simplified reasonably and also the concept of relative stiffness is introduced,which can be controlled by changing the thickness of the cross-frame.After series of simulations,it is can be found that the relative stiffness restricts the deformation mode of shipboard,which sign... |
