| 摘 要： | 通过RADIOSS显示有限元计算,对典型壁板结构的承载能力进行了计算分析,并与试验结果进行对比,验证了RADIOSS显式有限元计算分析的准确性。在此基础上,针对某民用飞机的机身壁板5种不同的典型壁板结构,分别在长度为200 mm和530 mm的情况下,采用有限元分析方法计算了长桁及壁板结构的压损和失稳情况,最终得出5种构型下的压损及失稳结果,为机身结构共性结构选型提供了数据支持。

| Abstract: | The carrying capacity of a typical panel structure was calculated that compared with experimental results to verify the explicit finite element calculation.Then five kinds of different panels′ crippling and buckling for a civil aircraft were calculated in a length of 200mm and 530mm,respectively.The results of five different configurations provide data for selecting common airframe structure. |
