The Finite Element Analysis and Size Optimization of a ROV Carrier Frame

The carrier frame is the installation base of ROV’s each subsystem and the main force component when lifted and recycled. Its research is designed to ensure sufficient strength, stiffness and weight as small as possible.In order to seek the optimal design proposal in initial stage of design, the finite element analysis and size optimization of one under researching ROV’s carrier frame are carried out.According to the result of optimization, the structural mechanics performance after optimization could basically remain unchanged, also the weight of the structural reduces 5.8 percent.
