摘要
将基于二次规划的准解析法优化理论应用于船体舱段的优化设计中,在整船三维有限元分析模型的基础上建立了船体舱段的优化模型.以船体舱段重量为目标函数,以钢板厚度和型钢横截面积为设计变量,考虑了尺寸约束、强度约束和稳定性约束,使优化后的舱段满足设计要求.根据优化理论编制了SAAOP程序,探讨了一种基于整体结构的局部优化设计的简便方法.
The method of optimization theory based on dual method is transplanted to cabin design, and the optimizing model of cabin is established. The target function is the weight of cabin, there are three kinds of constraints: dimension, strength and stability. The numerical results show that the structural strength after cabin optimized is fit. The SAAOP program based on optimization theory is designed, it is a brief method of local optimization design based on whole structure.
