摘　　要：太阳能铺板结构优化有利于解决局部应力、变形过大的问题,对三体复合动力无人艇的研究具有重要意义。本文建立太阳能铺板局部有限元模型,计算原结构的应力和变形量,基于多优化目标综合评估各优化方案的效果,得出最优方案。计算结果表明,所提出的优化方案在不损失布置面积的前提下,使结构最大应力降低了60.2%,最大变形降低了70.52%。该优化方案可大幅度降低太阳能铺板最大应力和变形,解决了局部强度问题,为复合动力无人艇结构设计提供了新的思路。The structural optimization of solar deck is conducive to solving the problem of local excessive stress and deformation,and is of great significance to the research and development of UsV(unmanned surface vessel)with multiple power source.A local FE(finite element)model of solar deck was established,the stress and deformation of the original structure were calculated,and the effects of optimization schemes were comprehensively evaluated based on multiple targets,and the optimal scheme was obtained.The results show that the proposed optimization scheme reduces the maximum stress by 60.2%and the maximum deformation by 70.52%without losing the layout area.The optimization scheme can greatly reduce the maximum stress and deformation of solar deck,solve the local strength problem,and provide a new idea for the structural design of USV with multiple power source.
