Abstract

Singapore Autonomous Underwater Vehicle Challenge (SAUVC) is an event organized IEEE Oceanic Engineering Society that took place in Singapore. This competition delegate a valuable project where it combine academic work and learning with practical skill development engineering. In building and designing the AUV, the critical component that should be taken into consideration is body structure. Objective of this project is to produce a design concept that can be used to compare to the existing design. Software used in this project is CATIA V5R16 for Computer Aided Design and using Ansys Fluent for Computational Fluid Dynamics. There are 5 concepts that had been proposed in this project and the selection method used to select the champion concept is using Pugh’s Selection Chart and Weighted Decision Matrix. After choosing the champion concept, that it will be proceed on 3D modelling and analysis on the body structure. The analysis is chosen based on the vector field, streamline, and contour and drag/lift coefficient and based on this analysis, the new and existing design will be compared and determined which design would be more suitable to be used in the next SAUVC event
