利用非线性动力显式有限元程序ANSYS/LS-DYNA对硬质聚氨酯泡沫夹层板受爆炸载荷作用下的动力响应过程进行了数值模拟,分析了泡沫体长度、支撑情况对结构动力响应特性的影响,为夹层板在防护工程领域中的应用与设计提供了依据。
The dynamic response of rigid polyurethane foam sandwich panels subjected to blast load was numerically simulated by the nonlinear dynamic explicit finite element program ANSYS / LS-DYNA. The influence of foam length and support on the dynamic response of the structure was analyzed , Provided the basis for the application and design of the sandwich panel in the field of protection engineering.
