Abstract

Abstract: Optimizing composite laminates with ply angle as a design variable poses challenges such as multiple design variables, susceptibility to local optima, and multiple solutions. To address the problems, a fiber ply angle optimization method based on lamination parameters is proposed in this paper. The method consists of two stages: optimizing of lamination parameters and converting the optimized lamination parameters into the corresponding fiber angle distribution. The relationship between lamination parameters and fiber ply angle and feasible region of lamination parameters are given, and the optimization mathematical models are established respectively. Numerical examples show that the fiber ply angle is improved, the stiffness and strength of the shell structure are enhanced. The feasibility and effectiveness of the method have been verified.
