Optimal Arrangement of Stiffeners Using PSO with Cloning Improvement

Abstract:

In the paper an application of the particle swarm optimizer (PSO) with cloning improvement to optimization problems is presented. Reinfored structures considered in this work are dynamically loaded and analyzed by the coupled boundary and finite element method (BEM/FEM). The method is applied to optimize location of stiffeners in plates using criteria depended on displacements or stresses. Numerical examples demonstrate that the combination of the PSO with the BEM/FEM is an effective technique for solving computer aided optimal design problems, both with respect to accuracy and computational resources.
