摘要
研究钢-硬质泡沫塑料夹层结构的特性,基于夹层结构的材料性能和力学理论,结合大变形动力学数值计算方法,通过比较夹层板在碰撞仿真中的建模技术,探讨适合于夹层结构的建模方法。
The character of the steel-polyurethane sandwich is studied. Based on the material properties and mechanics of sandwich, combined with large deformation dynamic numerical method, compared the different modeling techniques in the collision simulation, the thesis discusses the proper finite element modeling method for sandwich. The excellent impact resistance of sandwich is proved by simulated calculation.
