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 re-duce 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.
