Abstract
The purpose of this work is to demonstrate the application of a robust design
procedure to the design of aircraft structures. Taguchi’s method of robust design
has been applied to obtain the most appropriate values of a set of control factors
considering several noise factors. The goal is to maximize the robustness of the
design and decrease the loss of quality. A description of the methodology is
provided and an application example is solved, using a selected set of noise and
control factors, to describe the suitability of this technique for structural design
in problems where inaccuracies are present. The results show an improvement in
the response of the components, maintaining a low dependence on input value
variations and producing designs that increase the quality level and enhance the
robustness. Other different sets can be defined, as the method is completely
general.
Keywords: robust design, Taguchi methods, aircraft structures.
1 Introduction
Robust analysis improves the capabilities of uncertainty quantification
techniques because considers a function representing robustness, which is
optimized in the procedure.
Structural problems in aerospace engineering take place in an environment
where many parameters required for the mathematical formulation of the
problem do not have precise numerical values and some degree of uncertainty or
inaccuracy exists. A deterministic analysis may be unable to provide the amount
of information required by designers and thus other approaches taking into
account uncertainties are necessary. That circumstance also requires for
designers to be aware about the variations on the performance of prototypes,
