| Итог: | The design, material selection, manufacture and assembly of aircraft
structural elements are critical issues in the aviation industry. This study aims
to optimize the selection of joining methods of aircraft honeycomb panels by
considering strength, cost, and weight parameters. Accordingly, panel type,
panel thickness and joining methods were determined as input parameters,
and fracture force, displacement, cost, and weight as output parameters.
Tenon-mortise, double-sided bracket, single-sided bracket, and extrusion
methods were investigated for L and T-type panels. Panel thicknesses were
determined as 10 mm and 22 mm according to standards. Tensile test and
finite element analysis were applied to the samples to examine their
mechanical behavior. The weight and cost of the panels were determined by
the process analysis. The obtained findings were optimized according to
multi-criteria decision making and response surface analysis methods. In the
optimization model, maximization of tensile strength and minimization of
displacement, cost and weight was determined as the target function. At the
end of the study, the optimum thickness value for both types of panels was
determined as 22 mm, and the optimum joining method was tenon-mortise.
