某型飞机平尾普通梁腹板采用了减轻孔和加强槽的设计,对这种梁腹板在剪切载荷作用下的临界屈曲应力进行了有限元计算,并与无减轻孔和加强槽平板的临界屈曲应力进行了比较。
The design of the reduction hole and the reinforced slot of the flat beam normal beam web of a certain aircraft is carried out. The critical buckling stress of the beam web subjected to shear load is calculated by finite element method. The critical buckling stress is compared.
