Intergarting Jellyfish seach optimizer with finite element method to optimize structural weight under multiple natural frequency constraints

Abstract

This study aims to intergate Jellyfish search (JS) optimizer with the finite element method (FEM) to optimize structural weight under multiple natural frequency constraints. The proposed model (JS-FEM) is applied to to solve three weight optimization problems, including a 37-bar truss, 72-bar truss, and 600-bar single layer dome truss. Results obtained by JS-FEM are validated by literatures, and indicate that JS-FEM not only can find better results but also use fewer number of structural analysis (NSA). Therefore, JS-FEM is an effective tool to optimize structural weight under multiple natural frequency constraints.

Keywords: Jellyfish search optimizer, finite element method, metaheuristic optimization, natural frequency constraints.
