Abstract
In this study, finite element analysis of LPG cylinder is performed to enhance the service life. Maximum von mises, longitudinal, hoop stresses and deformation is analyzed to predict the structural failure at services, Test, minimum burst and expected burst pressures of 2, 3, 6 and 8 MPa respectively. The main components of LPG cylinder are inner high density polyethylene (HDPE) liner, upper cap assembly, winded composite layer and composite center hoop, which are designed in 3-D modeling software and then finite element analysis is performed on them. After number of analysis, the material properties are suggested as E-glass/Vinylester from 70 ° to 20 ° fiber angle from upper to lower side. The helical part of cylinder has a layer of E-glass / Vinylester 15 ° and an extra layer of hoop part with E-glass / Vinylester 90 °. The von mises criteria predicts that the weakest point of structure lies in the compostie hoop, so it is recommended to make this part strengthen as much as possible.
