基于简化解析方法的舷侧结构碰撞吸能分析

Analysis on Energy Absorption of Ship Side Structures in Collision Based on Simplified Analysis Method

船体结构破裂前因产生塑性变形而吸收能量的能力是衡量结构耐撞性的重要指标之一,提出一种简化解析方法对船舶舷侧结构的基本构件梁和板进行吸能能力计算,并将该方法应用于单壳船舷侧结构的碰撞分析。通过系列计算结果比对,从防撞角度对舷侧结构设计提出合理建议。

Energy absorption of ship structure caused by plastic deformation before its fracture is a key index.for measuring its crashworthiness. In this paper, a simplified analysis method is proposed to calculate energy absorption of ship panel and beam, as well as to analyze side structure in collision of single-hull ship. By comparing a series of calculation results, some suggestions for anti-collision ship side structure design are presented
