Modeling and Structural Analysis of A Pressure Hull under Dynamic Load
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
Pressure hulls are the main load bearing structures of naval submarines, and autonomous underwater vehicles (AUVs). A pressure hull is a structure that is designed to withstand the compressive forces associated with hydrostatic pressure. In this thesis, the assembly of the pressure hull including Navigation compartment shell, Battery compartment shell which are connected with bolts is designed which is used at present. Around 16 M12 bolts are used to connect the Navigation compartment shell and Battery compartment shell. These shells are to be dissembled very frequently for battery charging and other maintenance purpose. It is observed that the dissembling and assembling process is a very time consuming because it requires unbolting and bolting of all the 16 bolts every time. A new design of pressure hull is proposed where the bolts are removed and the navigation compartment and battery compartment are welded. In the present paper, design calculations are done as per ASME codes to withstand the pressure of 65 Bar. The design constraints considered for the analysis were stresses and deflections. The pressure hull have been modeled considering the elliptical cross section. The modeling of the pressure hull has been carried out by pro-5.0 and analysis soft ware is ansys 14.0 soft ware packages.
