Method and system for determining inflation pressure of IV-type vehicle-mounted hydrogen storage cylinder

The invention discloses a method and system for determining the inflation pressure of an IV-type vehicle-mounted hydrogen storage cylinder, and relates to the technical field of engineering manufacturing. The method comprises the following steps: carrying out buckling analysis on a three-dimensional finite element model of the gas cylinder lining to obtain a critical buckling load; according to the fiber winding angle of the winding fiber, the total thickness of the annular fiber, the total thickness of the spiral fiber, the thickness of the annular winding single layer and the thickness of the spiral winding single layer, the winding tension of each layer of winding fiber on the IV type vehicle-mounted hydrogen storage cylinder is calculated; obtaining the residual tension of the winding fiber according to the winding tension when the winding fiber is wound; according to the residual tension of each layer of winding fiber and the winding tension of each layer of winding fiber, obtaining ...
