摘　　要：蒙皮典型搭接结构是飞机进行疲劳设计的重要结构件之一,其附加弯矩分析一直受到工程上的广泛关注。采用一维平板壳单元,通过合理的模型建立,对飞机机身蒙皮典型搭接结构进行分析,计算得到搭接结构各疲劳细节点所对应附加弯矩。同时还对一维平板壳模型进行了验证,证实其计算的有效性。所得附加弯矩计算结果对飞机机身蒙皮典型搭接结构疲劳设计具有直接参考价值。As an important structural component of a plane in its fatigue design,typical single-shear lap joint usually requires the analysis of its secondary bending. With the flat shells, by rational modelestablishing and analysis, the papergot the secondary bending of all fatigue detail points. At the same time, the paper validated the flat shells method. The calculation results and conclusionspresented in the paper are of reference value for the fatigue design of airplane’s typical single-shear lap jointstructures.
