ROV的框架及内部布局设计是潜器能否可靠作业的关键之一。针对框架结构设计中轻量化问题，以最大位移和总质量为优化目标，设计一款ROV主框架结构。分析了ROV在3种不同工况下的受载情况，利用水动力与有限元分析得到ROV框架的应力与位移云图，并根据仿真结果首先对应力和位移最大的工况进行响应面优化，再将优化后的结果代入另外2种工况进行校核。优化后的框架结构最大应力以及最大位移均满足设计要求，通过优化，ROV主框架质量减少14.6%。最后通过后期的装配以及测试，验证了设计的可行性，为后续ROV框架结构设计提供宝贵经验。
The framework and internal layout design of ROV are one of the key factors for the reliable operation of the submersible.Aiming at the lightweight problem in frame structure design, a ROV main frame structure is designed with maximum displacement and total mass as optimization objectives. Loading conditions of ROV frame are analyzed under three different working conditions, at the same time the stress and displacement cloud map of the ROV frame are obtained by using hydrodynamic and finite element analysis. Based on the simulation results, first optimize the response surface for the working condition with the maximum stress and displacement, and then substitute the optimized results into the other two working conditions for verification.The maximum stress and displacement of the optimized frame structure meet the design requirements. Through optimization, the mass of the ROV main frame has been reduced by 14.6%.Finally, the feasibility of the design is verified through assembly and experiments and providing valuable design experience for the subsequent ROV frame design.
