摘要
船舶碰撞是在巨大冲击载荷作用下的一种复杂非线性瞬态响应过程。对于常用的小型艇而言,其体积小、总体结构刚度比较弱,因而对于碰撞所带来的破坏性更为敏感。本文运用MSC.dytran计算程序建模计算,着重分析小型艇舷侧结构碰撞损伤特性,最终获得了小型艇的碰撞损伤主要是艇体的总体弯曲变形,损伤变形区域占全船的比例较大,且艇体结构通常不会出现断裂破坏等相关结论。
Ship collision is one kind of complex nolinear transient response process under huge impact load.For the commonly used boats,due to their small size and relatively weak overall structural stiffness,they are more sensitive to the damage caused by ship's collison.The simulation model was run by using MSC.dytran computational procedure,by which this paper emphatically analyzes collision damage characteristic of the boat's side structure,and finally obtain some related conclusions:the collision damage of boats mainly is the overall bending deformation of hull,the damage deformation region accounts for a large proportion of the overall boat,and usually there won't be fracture failure on the hull structure.
