| Abstract: | The conceptual design of a pressure hull
design for an underwater pole inspection system is presented in this
study. One of the critical elements in
designing the pole-climbing robot is an enclosure for the electronic components
that can sustain high pressure and with good protection for underwater
application. Four main steps are required in designing the system: selection of
the shape of the hull, material selection, hull thickness requirement based on
depth limit and safety factor, and end closures design compatible with the hull
and design requirements. This study suggests that the preferable material for the
proposed structural construction of an underwater pressure hull is aluminum
alloy 6061-T6. The methodological approaches applied in the design criteria
include analytical calculation and a numerical method for results verification
based on the circular cylindrical shape. This paper also proposes that these
underwater structures should be able to operate up to 200 m depth. |
