AXIAL SHORTENING ANALYSIS OF CARBON FILAMENT-WOUND PRESSURE CYLINDER WITHTITANIUM ALLOY LINER AFTER HYDROSTATIC TEST

Abstract

Abstract: Aiming at the axial shortening phenomenon of the carbon filament-wound pressure cylinder with titanium alloy liner after hydrostatic test, the finite element software ANSYS was used to carry out the simulation calculation. Through the analysis of the displacement and strain calculation results of the cylinder body and dome, it is clarified that the fundamental reason for the axial shortening of the cylinder after hydrostatic test is outwardly residual deformation of the dome, and it will be conducive for the cylinder to optimize structural design and improve dimensional stability.

Key words: composite cylinders, carbon fiber, titanium alloy, finite element
