对某航空发动机复合材料外涵道机匣构件进行了结构有限元建模与线性屈曲特性的有限元分析。利用圆柱壳体耦合载荷的研究成果 ,分析了机匣在轴向压力、端部扭矩及内压组合作用下的屈曲行为规律 ,进而为航空发动机的结构设计提供了参考依据。
Finite element analysis of structural finite element modeling and linear buckling characteristics of aeroengine composite outer duct receiver components was carried out. Based on the research results of coupled load on cylindrical shell, the buckling behavior of the casing under axial pressure, end torque and internal pressure is analyzed, which provides a reference for structural design of aeroengine.
