| 摘 要： | 用细化有限元模型网格的方法来模拟金属波纹拱壳屋顶结构实际的波纹形状是一种有效的分析方法 ,但却使得网格非常密集 ,有限元模型比较复杂。应用有限元网格自动剖分理论 ,采用平面超单元变换剖分法 ,编写程序实现了金属波纹拱壳结构有限元模型网格的自动剖分 ,大大节省了计算机建模时间 ,并避免了在手动建模及划分有限元网格时所出现的误操作

| Abstract: | To simulate the actual wave shape of metal corrugated arch shell roof structure by subdividing the grids of finite element model is an effective analytical method,but that causes the grids to be very dense and the finite element model also to be more complicated A program is compiled to realize the automatic division of the finite element grids of metal corrugated arch shell structure using the theory of automatically dividing the finite element grids By using the program,the time that computer takes to establish model can be saved,and the false operation due to manually establishing the finite element model and dividing the grids can be avoided |
