The Ply Stacking Optimization for Composite Laminated Structure: Application of Tabu Search Algorithm

Abstract

In this paper, tabu search algorithm, the laminated overlay has been optimized. The total thickness of the laminated structure under certain circumstances, to composite laminates maximum system reliability indices as the objective function, the composite fiber orientation angle and relative thickness of the optimized design. It is through the local neighborhood search mechanism and the corresponding tabus to avoid circuitous search criteria and standards to cut through the broken tabu excellent release from the state, thereby ensuring a variety of effective exploration in order to ultimately achieve global optimization. This article is laminated overlay design provide a new and efficient framework, the framework of the algorithm relative to the previously used method has obvious advantages: After a limited number of cycles that can converge to satisfactory results, the optimization process shows good robustness of the algorithm, and the method to solve the structural optimization of composite materials and other combinatorial optimization problems provide a new way of thinking. This paper describes the basic idea of tabu search algorithm, composition, processes, principles, and so on.
