Abstract
In this paper, the 70 Mpa vehicle-mounted type IV hydrogen storage cylinder fully wound by carbon fiber with plastic liner is studied. Based on the analytical method, the analytical analysis model of fiber-wound hydrogen storage cylinder is built to obtain the functional relationship between fiber winding parameters and the external pressure of the liner. In addition, the critical buckling load of the hydrogen storage cylinder liner is obtained through the finite element method. The mapping relationship between fiber winding parameters and anti-instability inflation pressure is constructed; a calculation method of anti-inflation pressure in the process of fiber winding of type IV hydrogen storage cylinder is proposed, and the effect of inflation pressure with the increase of fiber winding layer is studied. The calculation method of inflation pressure can provide theoretical guidance for the selection of inflation pressure in the manufacturing process.
