基于分段动态松弛协同优化算法的船舶机舱结构优化设计
Optimization design of ship engine room structures based on sectionalized dynamic relaxation collaborative optimization method
摘要
Abstract
Based on the standard collaborative optimization and aiming at its inherent flaws such as high sensitivity to the initial guess and slow convergence, this paper combines the collaborative optimization al⁃gorithm, the hybrid optimization algorithm, and the dynamic relaxation method to put forward a sectional⁃ized dynamic relaxation collaborative optimization algorithm. The proposed algorithm can be applied in the multi-objective optimization of ship engine room stuctures. Meanwhile, the multi-objective collaborative optimization model of the main ship engine room is established to solve the static and dynamic, multidisci⁃plinary and multi-objective optimization of ship engine room structures. Then, the collaborative optimiza⁃tion is validated through the Isight software to draw the optimal solution. It is shown that the step-by-step dynamic relaxation collaborative optimization algorithm achieves both accuracy and efficiency compared with that based on the genetic algorithm, which provides great references to the multidisciplinary and multi-objective design optimization of more complex structures in real projects.关键词
