Structural Analysis on Frame-Cover of USV Robot

Abstract

This paper presents a structural analysis result on the frame-cover structure of the unmanned surface vehicle (USV) for connecting with the remotely operated vehicle (ROV). The analysis based on the finite element method (FEM) is carried out to verify structural integrity of the frame-cover structure of the USV on condition of the maximum loaded weight and propeller thrust forces. For FEM modeling the detailed parts of the USV with the frame-cover, inflatable boat small (IBS), welded frames and FRP covers are defined with actual mechanical properties and boundary conditions. As result of the structural analysis, the overall displacement and maximum stress of the whole ship structure is verified to improve its structural design.
