Abstract: A method for optimizing a layer-stacking sequence of a composite material pressure vessel. includes determining design variables of a to-be-optimized composite material pressure vessel based on design objectives thereof, the design objectives including a liner size and a working pressure of the composite material pressure vessel, and the design variables including filament winding angles, winding layer thicknesses, and winding layer quantities; establishing a finite element model based on layer-stacking information and boundary conditions of the to-be-optimized composite material pressure vessel, the layer-stacking information being the design variables; modeling the liner of the pressure vessel by solid elements, and modeling composite material layers of the pressure vessel by continuum shell elements. The method includes obtaining required optimization objectives based on the established finite element model; and establishing an optimization model based on the optimization objectives, and obtaining, through iterative optimization, an optimal layer-stacking sequence of the composite material pressure vessel.
