摘要
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。
The structural finite element modelling and the finite element analysis of linear buckling characteristics of the composite by pass duct case of aeroengine are carried out. By using the cylinder buckling theory, the buckling behavior of the case under the combination of axial load, end torque and internal pressure is analyzed in the paper, so as to give the reference to the structure design of aeroengine.
