Abstract

An optimization approach for composite marine structures has been presented. The natural frequency of a fiber-reinforced 3D wing has been calculated using finite element method(FEM). In order to prevent flow induced resonance, the natural frequency has been designed to be far away from the exciting frequency of hydrodynamic response by optimize the fiber stacking sequence. In addition, the hydrodynamic forces was computed by solving the URANS(Unsteady Reynolds Average Navier-Stokes) equation. First, the Kriging surrogate model has been conducted as a black box function having the stacking sequence as input and the natural frequency as output. An efficient global optimization process was then carried out to improve the accuracy of the surrogate model. Finally, a multiobjective optimization genetic algorithm has been employed to generate a Pareto solution. The results show that optimization approach is feasible for frequency based design of composite wing.
