摘要: 针对港珠澳大桥建设项目,对大桥防撞护舷系统技术指标进行了验证,并进行船舶碰撞有限元数值模拟,旨在对防撞护舷系统的安全性及结构设计的合理性进行评估,通过有限元分析软件ANSYS/LS-DYNA对船只碰撞防撞护舷进行非线性模拟仿真,得到计算工况下的碰撞能量和碰撞力时程曲线,同时对复合材料防撞护舷的结构设计和材料选用也进行了分析工作。

Abstract: For the project of Hongkong-Zhuhai-Marco bridge construction, this study verified the technical requirements of anti-collision fender system of bridge, and did finite element numerical simulation of ship collision in order to evaluate the safety of anti-collision system and the rationality of structural design, did nonlinear simulation on ship collision to the fender with FEA software ANSYS/LS-DYNA, meanwhile this study also did analysis on structural design of FRP anti-collision fender and the selection of materials.

Key words: anti-collision fender, time history curve, steel boxed cofferdam, ANSYS/LS-DYNA, numerical simulation
