Analysis of a Large High Pressure Vessel Closure

Abstract

Design of the end closure for a high pressure vessel is never an easy task. However, in this case it is complicated by a requirement for quick operation and high reliability. The configuration which has best proven itself many times is the screw block breech. This report covers an analysis of this closure which is a five-body problem. The problem is further complicated by the fact that the bodies interact on eight contact surfaces. This analysis will point to a fatigue failure at a single point in the structural system. Keywords: Breech mechanisms; Finite element analysis; Stress concentration; ABAQUS computer program; Contact surface deformation; Stress analysis; Screw threads.
