This paper imported agent model which represented the stacking sequence. Then the stacking sequence parameters, buckling eigenvalue and cured deformation with different stacking sequence were analyzed by numerical experiments. Then, the response surface models of cured deformation vs stacking sequence parameters and buckling eigenvalue vs stacking sequence parameters were constructed separately. Further, the optimization of cured deformation was constructed to find the best stacking sequence parameters. Lastly, the actual stacking sequence was gained by a stacking sequence reverse design on the related stacking sequence parameters. The results show that the optimization method of stacking sequence can reduce the cured deformation subjected to stability constraint, and can improve the efficiency of optimizing the stacking sequence based on the agent model observably.

引入反映铺层顺序的代理模型,通过数值实验计算了不同铺层顺序下结构的铺层顺序参数,失稳特征值和固化变形大小,在此基础上分别构造了固化变形和失稳特征值对铺层顺序参数的响应面模型,并根据所得响应面模型优化得到最优的铺层顺序参数,再通过铺层顺序的反向设计得到实际的铺层顺序。结果表明:在满足结构稳定性约束条件下,通过铺层顺序优化可以减小固化变形大小,基于代理模型的铺层顺序优化方法可以显著提高铺层顺序的优化设计效率。
