Theoretical Investigation on Prestress during the Manufacturel Process of Integrated Multilayer Wrapped Pressure Vessel

摘要

Integrated multilayer wrapped pressure vessel is widely used in process industrial production. In allusion to its manufactural process and structural characteristics as well as considering the frictional force between the laminates in the relative displacement of the laminates, the calculation formulae in the laminate or the inner cylinder prestressed by the wrapping force of the hydraulic manipulator were derived by principles of mechanics. The investigative results of the prestress distribution in the integrated multilayer wrapped vessel structure have a certain direct significance for its actual manufacture and insuring its manufactural quality.
