摘要
通过对冰与钢-泡沫夹层结构的冲击特性进行有限元仿真建模计算,得出其相关碰撞特性;同时计算得到的接触部位的压强和面积关系与ALIE所规定的压强-面积曲线作比较,确定材料模块选取的合理性。进而为系统研究冰与夹层结构以及船冰碰撞之间的耐撞性提供一定参考意见。
According to numerical simulation of ice and steel- foam sandwich structure in the collision processing, relevant collision characteristics are obtained. Meanwhile, through comparing the relationship of pressure and contact area of ice and steel-foam sandwich structure, rationality of material module is determined. Then it provides a reference for studying crashworthiness of ice and steel-foam sandwich structure and iceberg and ship.
