2008北京奥运会开幕式“大型纸”的设计与分析

Analysis and design of large paper at 2008 Beijing Olympic Games opening ceremony

阐述了2008北京奥运会开幕式中"大型纸"的设计与分析方法,由于其平面尺寸较大,结构较柔,为满足设计要求,创造性地采用了新型蜂窝复合材料,通过有限元分析与设计满足了表演的要求。采用真空无缝内置加强带粘结技术和玻璃钢内衬钢套节点,解决了500m^2超大规模的蜂窝板拼缝连接及"大型道具纸"连接处的局部应力集中问题,为类似大型表演活动道具的设计提供了参考。

Based on the principle of virtual work,a first discrete,after using Euler-Madaurin sum formula of the sum that is the hollow cylinder transverse direction equivalent thickness of the numerical solution.And on the method of calculating results using the finite element numerical simulation analysis.Contrast this paper shows that the numerical solution for the larger span,the results more satisfactory accuracy,can be used for design,
