摘要: 针对以铺层角度为设计变量优化复合材料层合板存在的设计变量多、易于陷入局部最优解和多解性问题,引入层合参数和Lobatto多项式,提出了基于层合参数的纤维铺角优化方法。该方法分为优化层合参数和将优化后的层合参数分布转换为与之对应的纤维铺角分布两个阶段。给出了层合参数与纤维铺角的关系式和层合参数可行域,分别建立了相应的优化数学模型。数值算例表明,该方法改善了纤维铺角布局,提高了壳结构的刚度、强度和收敛性,验证了其可行性和有效性。

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.

Key words: composite shell structure, lamination parameters, ply angle optimization, Lobatto polynomial
