航空发动机复合材料机匣屈曲特性的有限元分析
FEA Method for the Critical Buckling Load of Aeroengine Composite Case
-
摘要: 复合材料是60年代出现的一种性能优异的新型材料,目前复合材料在航空航天结构领域里已得到了一些的应用。本文利用线性板壳理论和线性屈曲模型,针对某航空发动机树脂基复合材料外涵道机匣构件及此材料层合板进行结构有限元建模与屈曲特性的有限元分析,以期为航空发动机的结构设计提供参考依据。Abstract: The advanced composite material as a new material has been developed since 1960′s.Now laminated continuous fiber-reinforced composite materials are being used in some primary components in aircraft structures.Using linear shell and buckling theory and modeling finite element,this paper analyses the buckling of laminated plate and composite aeroengine case.At the same time some advice on engineering design is given.
