摘 要: 对单层球面网壳结构在集中冲击作用下的弹塑性响应进行了有限元分析,得到了网壳结构的节点位移和杆件轴力响应时程以及能量分布,给出了网壳结构响应随冲量参数变化的规律,并将部分计算结果与相关试验进行了对比. The finite element method is validated to analyze the elastic-plastic dynamic response of the single-layer lattice shell subjected to the concentrated impact. The computational results are obtained,such as the displacement-time history of nodes,the axial force-time history of members and the energy-time history. The change of structural response with impact parameters is also obtained. Moreover,some analysis results are compared with the correspond-ing test data.
