[摘要] 闡述了2008北京奧運(yùn)會(huì)開(kāi)幕式中“大型紙”的設(shè)計(jì)與分析方法，由于其平面尺寸較大，結(jié)構(gòu)較柔，為滿(mǎn)足設(shè)計(jì)要求，創(chuàng)造性地采用了新型蜂窩復(fù)合材料，通過(guò)有限元分析與設(shè)計(jì)滿(mǎn)足了表演的要求。采用真空無(wú)縫內(nèi)置加強(qiáng)帶粘結(jié)技術(shù)和玻璃鋼內(nèi)襯鋼套節(jié)點(diǎn)，解決了500rri2超大規(guī)模的蜂窩板拼縫連接及“大型道具紙”連接處的局部應(yīng)力集中問(wèn)題，為類(lèi)似大型表演活動(dòng)道具的設(shè)計(jì)提供了參考。

Abstract: Based on the principle of virtual work, a first discrete, after using Euler - Madautin 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.
