Fatigue load optimization and test verification of the full-scale aileron
In the fatigue test of aircraft wing structural components
the fatigue design loads need to be optimized so as to reduce the bending
shear and torsion load errors applied during the test. Firstly
taking the full-scale aileron as the research object
the fatigue test load optimization model was established; then the objective function was solved by using the weighted summation method
and the optimized load at each loading point were obtained. The results show that the load is more suitable for loading design than the load assigned by the minimum energy method
and the load distribution is closer to the design load. Finally
the full-scale aileron fatigue test was designed and carried out
and the test strains were basically the same as the calculated results. It proves that the model can be used for fatigue test load optimization of large-scale components.
