| 摘 要： | 为考察飞机典型复合材料加筋壁板结构的稳定性及破坏强度，本文将计算在轴压载荷下，复合材料加筋壁板结构的失稳载荷及破坏载荷。通过对稳定性试验、有限元计算、工程算法3种方法结果的比较，摸清复合材料加筋壁板在轴压载荷下的稳定性和极限承载能力，找出壁板失稳规律，为今后的复合材料加筋壁板稳定性计算提供理论依据。

| Abstract: | In order to review the stability and failure intensity of composite stiffened wing panels, this report has calculated buckling loads and failure loads in axes pressure. Comparing testing result with finite elements account and engineering account, the conclusion will find out stability rule and high-point carrying capacity in axes pressure and bring theoretical gist with the stability account of composite stiffened wing panels. |
