摘要:
为求解大跨度充气膜结构的准确形态,阐述了一种形态分析方法.分析流程为构建初始形、假定初始态、迭代求解预应力及变形、逆向变位改变初始形、逆位移形再迭代计算、求得平衡形态.以某充气膜结构为例计算,平衡形态下最小von mises应力为0.723×106 N/mm2,最大von mises应力为13.4×106 N/mm2.平衡构型下形面误差分析结果:最大变形δmax为0.014 5 m、平均变形μ为0.002 11 m、变形均方差σ为0.001 68 m,计算精度满足要求.最后介绍大跨度充气膜结构的工程应用实例.
Abstract:
In order to solve the accurate morphology of large-span inflatable membrane structures,a morphological analysis method is proposed. The analysis process is to construct the initial shape,assume the initial state,iteratively solve the prestress and deformation,change the initial shape by reverse displacement,and then iteratively calculate the inverse displacement shape to obtain the equilibrium shape. Taking an inflatable membrane structure as an example,the minimum von Mises stress is 0.723×106 N/mm2,and the maximum von Mises stress is 13.4×106 N/mm2. The results show that the maximum deformation δmax is 0.014 5 m,the average deformation μ is 0.002 11 m,and the deformation mean square error is 0.001 68 m. The calculation accuracy meets the requirement. Finally,an engineering application of large span inflatable membrane structure is introduced.
