| 摘 要： | 针对爆炸载荷作用下的聚脲钢板复合结构，基于非线性有限元软件LS-DYNA，利用CONWEP算法对聚脲复合钢板结构在爆炸载荷作用下的结构变形进行数值模拟分析，并与试验结果进行了对比.结果表明，CONWEP算法能够很好的模拟聚脲钢板复合结构在爆炸载荷作用下的变形.在相同钢板厚度条件下，聚脲钢板复合结构的最大变形挠度要小于裸钢板结构.从吸能特性来看，聚脲弹性体有良好的吸能特性，聚脲钢板复合结构中钢板的吸能要低于裸钢板，使得复合结构中钢板的变形要小于裸钢板.

| Abstract: | Based on the nonlinear finite element software LS-DYNA, the deformation of polyurea steel plate composite structure under explosive loading was simulated by using CONWEP algorithm. The simulated results were compared with the experimental results. The results show that the CONWEP algorithm can well simulate the deformation of polyurea steel plate composite structure under explosive loading. With the same steel plate thickness, the maximum deformation deflection of polyurea steel plate composite structure is smaller than that of bare steel plate. From the results of energy-absorbing, polyurea elastomer has good energy-absorbing characteristics, and the energy-absorbing of steel plate in composite structure is lower than bare steel plate, which makes the deformation of steel plate in composite structure is also lower than that of bare steel plate. |
