A Finite Element Analysis of the NPS Autonomous Underwater Vehicle (AUV) Hull Intended to Operate in Deep Waters

Abstract

The Naval Postgraduate School AUV, named ARIES, was intended to operate in shallow waters. Its utilization as a server vehicle can requires to dive deeper. The purpose of this project is to check if the structure of the ARIES is able to go in deep diving depth. A Finite Element Analysis (FEA) of the hull is used. FEA is the most common structural analysis tool. This report illustrates the different steps made to process the FEA. A first analysis is performed to check the structural behavior of the hull for shallow waters (until 100feet). A second analysis is made for deep waters. Some solutions to strengthening the hull are presented. Several type of stiffeners can be used.
