撞击参数对双层舷侧结构碰撞响应的影响

深入了解船体结构碰撞损伤特性和能量吸收机制是开展船舶耐撞性优化设计的前提。文章利用显式非线性有限元数值仿真技术对不同撞击条件下的双层舷侧结构碰撞响应进行了系列研究。研究结果表明：撞击位置、撞击角度和撞击速度的改变可能导致不同的碰撞损伤过程或结构损伤变形。

Influence of Impact Condition on Behavior of Double Side Structure in Collision

In structural design and optimization of double hulled ships,it is important to understand the behavior of their structures and energy absorption mechanism in collision events.In this paper,the influence of collision condition on structural response of double skinned side structure is investigated by explicit nonlinear F.E.numerical simulation technique.The results show that the damage behavior of double side structure is in close relationship with position,angle and speed of collision.
