船与刚性桥墩的碰撞性能分析

Analysis on Collision Characteristic of Ship and Rigid Pier

运用非线性有限元基本理论,采用国际上广泛使用的大型结构分析程序LS-DYNA,建立了船舶、刚性桥墩的三维有限元计算模型.分析了碰撞力的大小、船首及构件的损伤和吸能特性,并与经验公式计算结果进行了比较,得出了有关船撞力大小和分布规律的结论.

Based on the nonlinear finite element theory and the finite element analysis program LS-DYNA, the 3D finite element calculation modle of ship and collision-preventing device of the pier are built. The ship-bridge collision force, the energy absorption characteristic and damage of the ship structure are discussed. Meanwhile ,some instructive conclusions are also attained in this paper.
