Multilayer Paraboloid Structures Optimization of Using a Hybrid Charged System Search

Space structure is a rigid, lightweight, truss-like structure constructed from interlocking struts in a geometric pattern. Space structure can be covered large areas without intermediate supports.In this paper, the problem of simultaneous shape and size optimization of a three-layer paraboloid space structure is addressed. In this method, the hybrid charged system search-particle swarm is utilized as the optimization algorithm and the result is compared with the particle swarm optimization algorithm. The objective of this paper is to find optimal weight, that design variables are considered as height and cross-sectional area. For conducting this, a three-layer paraboloid space structure is designed by SAP and then optimized by using hybrid charged system search-particle swarm and particle swarm optimization algorithms. The result demonstrate the efficiency of the hybrid charged system search-particle swarm algorithm.
