Multi-objective optimization of the UAV wing by means of evolutionary computations

Adam Dlugosz

Abstract


The paper presents an application of the in-house implementation of the evolutionary multi-objective algorithm. Different types of functionals, which depend on equivalent stress, displacement and total mass of the structure are defined. Values of the functionals are calculated on the basis of results obtained from numerical simulations. Numerical model of the UAV wing, composed of different laminate materials has been prepared and verified experimentally. Automatic calculation of the fitness functionals for the parameterized model is prepared. Examples of multi-objective optimization by means of 2D and 3D Pareto-optimal set of solutions are presented. Effectiveness and usefulness of proposed method of multi-objective optimization are shown.
