Design And Analysis Of A Large Transportable Vacuum Insulated Cryogenic Vessel

Abstract

The CAD software Pro/Engineer (creo-2.0) is employed to see the models for the chosen designs. Additionally, the finite part module ANSYS WORK BENCH 14.5 is employed to get results of mechanical analyses so as to see if the stresses are among limits. During this thesis, 2 models of cyrogenic pressure vessels are modelled and analyzed for his or her strength and fatigue behaviour. One model of pressure vessel is with just one vessel and therefore the alternative pressure vessel with insulation that is created from inner vessel, outer vessel and surge plates. Static Analysis and Fatigue Analysis are performed on original pressure vessel, on insulated pressure vessel considering same material for inner and outer vessels & on insulated pressure vessel by considering different materials for inner and outer vessels and compared. The materials considered are Aluminum grade 5083, Stainless Steel and Steel grade 310 for inner vessel & Glass Carbon and S-Glass for outer vessel.
