| Summary: | Design of the structural supports has always been practically important in engineering applications. In addition to holding a structure properly, supports can also be utilized to improve the structural performances. In this study, by using finite element method (FEM) and Particle Swarm Optimization (PSO), the optimal support positions of structures is determined to minimize the maximum of bending moment in structure that is subjected to multi loads. PSO is based on the premise that social sharing of information among members of a species offers and evolutionary advantage. As compared to other design optimization methods, PSO is robust, more efficient, requiring fewer number of function evaluations, while leading to better quality of results. Results show that support position optimization can reduce the maximal moment significantly, and deserves more investigation. |
