摘要
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2000DWT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。
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 structural deformation and damage of the failure process were obtained. It provided the theoretical basis for the engineering design and experiment.
