飞机机体结构的内力计算是其结构强度分析的重要技术手段之一。外翼壁板直接承受空气动力载荷并把它传递到机翼纵向和横向构件上。探讨有限元截面法在外翼壁板内力计算中的应用,从理论分析以及实际操作的角度,为壁板强度计算流程化设计提供一种工程化分析手段。
The calculation of the internal force of aircraft fuselage structure is one of the important technical means of its structural strength analysis. The outer wing panels bear the aerodynamic load directly and transmit it to the longitudinal and transverse members of the wing. This paper discusses the application of finite element method in calculating the internal force of the outer wing panel, and provides an engineering analysis method for the calculation of the wall strength calculation flow from the theoretical analysis and practical operation.
