船与FRP浮箱非线性动力学碰撞过程的数值仿真

摘要

Introduced the structure characteristics of the locating crash FRP floating pontoon is introduced. Based on the platform ANSYS/LS-DYNA software, the nonlinear numerical simulation was carried out for a 2000 DWT bulk cargo ship with the floating pontoon considering the direction and 8° oblique collision. The process of energy dissipation and the impact force attention schedule and the collision zone of struc-tural deformation and damage of the failure process were obtained. It provided the theoretical basis for the engineering design and experiment.%　　介绍了自定位防船撞FRP浮箱的结构特点；基于ANSYS/LS-DYNA软件平台，对一艘2000 DWT散货船与防撞浮箱正撞和8°斜撞的非线性动力学过程进行了数值仿真研究；分析了能量耗散过程、碰撞力衰减时程以及碰撞区的结构变形与损伤失效过程；为该装置的工程设计与工程实验提供了理论依据。
