Design and Computational Analysis of the Integral Structure of Composite High-Pressure Vessel

摘要

The design approach of cylindrical type composite high-pressure vessel consisting of a metal liner and a composite shell is considered in this paper. An equation is presented for head geometry calculation. An estimation of angles and zones winding is performed based on the head form. The finite element modeling is carried out using shell and solid finite elements in ANSYS software. Detailed analysis of the structure stress-strain state is performed taking into account compatible working the liner and composite shell at the physical and geometrical nonlinear formulation. The thickness optimization of composite shell is carried out based on strength condition at the maximum stress criterion formulation under the proof load action. The obtained results demonstrate the effectiveness of the proposed approach to composite high-pressure vessel modeling and the desirability of the proposed design solutions.
