| 摘 要： | 从经典的层合板理论出发,根据钢-泡沫结构力学性能,引出钢-泡沫结构的本构关系。通过对钢-泡沫结构的冲击进行数值模拟,得出最大碰撞力与经验公式得出的最大碰撞力进行比较,确定理想的建模方式为铺层方法,进而对钢-泡沫结构的碰撞性能进行综合研究与分析,并为系统研究船舶耐撞性提供一定参考意见。

| Abstract: | According to the classical laminated plate theory in the article,with mechanical properties of steel-foam structure,constitutive relation of steel-foam structure is derived.Carry out numerical simulation of steel-foam structure in the collision processing,compare the maximum impact force from numerical simulation and empirical formula and determine that the superior modeling approach is Laminate.The collision characteristics of steel-foam structure could be analyzed comprehensively.Then it provides a reference for studying crashworthiness. |
