摘要
文章利用大型非线性动态响应分析软件MSC.Dytran,基于有限元碰撞理论对500t货船整船与焦港河大桥搭设便桥之间碰撞进行数值仿真研究。仿真主要研究了船艏结构损坏、碰撞力演变、能量传递和便桥应力变化,进而为焦港河大桥施工过程中搭设便桥提供参考。
Based on the theory of finite element collision, this article applies MSC. Dytran, an analysis software for nonlinear dynamic response, to the numerical simulation study of the head-on collision between a certain 500 t cargo ship and the auxiliary bridge of Jiao＇gang＇he Bridge from such angles as the damage to the bow of the ship, the transformation of the collision force, the energy transfer as well as the stress variation of the auxiliary bridge, which is expected to offer reference for the construction of the auxiliary bridge.
