钢-泡沫结构冲击性能的建模方法

摘要

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.%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.
