摘要
探讨如何运用协同优化方法解决多破损模式下船舶结构设计的优化问题。在协同优化方法的基本理论框架下,研究多破损模式条件下的结构并行设计和优化,建立相应的优化模型。以多破损模式下的船体结构静力学优化为例,运用协同优化方法进行优化计算,获得较好的破损残余强度。算例表明,协同优化方法能有效地解决多破损模式下的结构优化问题。
The purpose of this paper is to explore the application of collaborative optimization （CO） methods to solve the optimization problems of ship structure with multiple damage models. Based on the basic theoretical framework of collaborative optimization method, the parallel design and optimization of the structure with multiple damage models are discussed, and the corresponding optimization model is established. Finally, structural static optimization with multiple damage model for ship structure is taken as an example, in which, the collaborative optimization is applied, and the best residual strength of structural damage is obtained through numerical simulation. Numerical results indicate that, the collaborative optimization method can effectively solve the structure optimization problem with multiple damage models.
