The embodiment of the invention discloses a rigidity simulation method for a bearing type covering cap in a full-aircraft model, and the method comprises the steps: calculating the strain corresponding relation between the covering cap and a mouth frame through a static strength test of a wing structure with the bearing type covering cap; obtaining an initial overall strain and the strain corresponding relation according to a finite element analysis model, and determining a rigidity reduction coefficient of the covering cap; multiplying the stiffness reduction coefficient by an actual thickness parameter of the covering cap to obtain a revised thickness of the covering cap; and modifying the thickness of the covering cap in the finite element analysis model according to the revised thickness.

    本发明实施例公开了一种承载式口盖在全机模型中的刚度模拟方法,所述方法包括:通过带承载式口盖的机翼结构静强度试验,计算口盖与口框的应变对应关系;根据有限元分析模型获得初始总体应变和所述应变对应关系,确定口盖的刚度折减系数;将所述刚度折减系数乘以口盖的实际厚度参数,获得口盖的修订厚度;根据所述修订厚度对所述有限元分析模型中的口盖厚度进行修改。
