摘要:

建立了多用途船的舱段有限元模型,利用Matlab调用有限元软件,将粒子群算法(PSO)引入复杂船舶结构的优化中,实现了PSO对复杂船舶结构的优化,取得较好的结果,并与遗传算法的结果进行了对比, 验证了PSO用于复杂船舶结构优化的有效性.

Abstract:

This paper established a finite element model for the cargo areas of the multipurpose ship. It then implemented PSO to optimize complex ship structures using matlab to call the finite element software. This approach obtained relatively better results compared with the results obtained by using the GA algorithm, validating the application of PSO in the optimization of complex ship structures.
 

Key words: ship structures, optimization; particle swarm optimizer(PSO)
