基于协调共同规范的船体加筋板结构的优化设计方法

Analysis and Optimization Method of Ship Stiffened Panel Structures Based on HCSR Rules

基于协调共同规范,讨论船舶中剖面典型加筋板形式、优化问题和优化策略,编写优化设计程序。实船算例校核表明,在保持结构总钢重,同时满足规范要求的条件下,优化后的加筋板结构的屈曲能力有所提高,船体剖面的总体结构性能得到进一步改善。

Based on Harmonized Common Structural Rules, the typical stiffened panel forms of the mid-ship section, optimi- zation problem and optimization strategy is discussed about. An optimization program is developed and assessed by calculating typical ship structures. While keeping the weight of the stiffened panel structure unchanged, and satisfying the requirements of rules, the calculating results indicate that the buckling capacity of optimized stiffened panels is increased and the performance of the overall hull structure also has improved.
