Numerical simulation and research of the split ultrahigh pressure cylinder

Abstract

The pressure capacity of an ultrahigh pressure cylinder is the bottleneck of the development of ultrahigh pressure vessels. In order to improve the pressure capacity of the cylinder, the finite element software was used to analyse the single-layer thick-walled cylinder and the split cylinder under the same load. Research results show that the split cylinder has higher pressure capacity than that of single-layer thick-walled cylinder. Simulation of the different number subsections of the same size split cylinder show that the number’s increase of the subsections can effectively reduce their Von Mises stress under the same load.
