摘　　要：基于响应面方法,对加筋超压艇结构的加强筋间距、加强筋直径和筋间瓣幅曲率半径等设计参数进行优化设计。根据Box-Behnken试验方法设计结构分析样本点,采用有限元法获得样本结构的应力,利用响应面法研究加强筋间距L、筋直径d和瓣幅曲率半径R对超压艇筋间最大应力的影响,并拟合得到加强筋质量的二元二次响应面模型,建立加强筋质量为约束条件的结构参数优化函数。优化结果表明,加强筋间距、加强筋直径、瓣幅曲率半径3个设计参数具有强相关性,允许质量为未加筋结构的30%时,优化的超压艇结构可显著控制超压艇结构的筋间最大应力。The optimization design of super pressure airship structure parameters about tendons spacing,tendons diameter and segment curvature radius was studied based on the response surface methodology.The structures stress was obtained by finite element model whose parameters are selected by using Box-Behnken experiment method.The effects of tendons spacing,tendon diameter and segment curvature radius on max stress area between two tendons were investigated.The mass of tendons are predicted by quadratic equations.Finally,the optimization model under tendons mass constraint were established.The optimized results show that tendons spacing,tendons diameter and segment curvature radius strongly affect each other with the constraint of tendons mass.The max stress between two tendons can be reduced when tendons mass is 30%of the original unreinforced structure.
