Síntesis óptima de un mecanismo de cinco barras de 2-GDL utilizando técnicas de inteligencia artificial

This paper presents the optimal dimensional synthesis of a five -bar mechanism in order to minimize the force on the output link and ensure paths inside an established workspace. The synthesis is carried out by proposing a numerical optimization problem with constrains taking into account structural and force mechanism considerations. The Differential Evolution algorithm is 105 Research in Computing Science 113 (2016) pp. 105–118; rec. 2016-03-02; acc. 2016-05-15 used to solve the resulting optimization problem. A set of 30 independent executions of the algorithm is carried out and the best of the results achieved compared with other possible solutions. It is shown that the optimal mechanism has a better performance according to the selected objective function. In addition, parametric statistical results of the DE algorithm performance are shown; such results suggest a high performance of the DE algorithm for solving engineering design problems.
