摘  要:为了研究复合材料薄壁加筋结构舱段的在特定载荷下的稳定性,采用有限元方法仿真计算了在舱段薄壁厚度不变时,筋条截面积在200mm^2、300mm^2和400mm^2下,舱段稳定性随着筋条高度变化情况,得到了临界载荷,计算结果可作为工程设计参考依据。The finite element method has been used to study the stability of thin-walled reinforced composite material cabin under a particular cabin load.The change behavior of cabin stability has been find when the rib's height has been changed as it's was 200mm^2,300mm^2 and 400mm^2,though the thickness of the thin wall was constant.the critical load has been figured out,the results could be used as reference for engineering design.
