Abstract
Composite grid is made up of continuous fiber wound oblique and hoop ribs and the skins. Based on laminated plate and beam element of Mindolin first-order shear deformation theory, the ribs and the skins of the composite grid were simulated. Through space coordinate transformation and geometric continuous condition, the element tangent stiffness matrix for the composite grid structure was obtained. Bucking finite element numerical simulation method for the composite grid structure was given. The composite grid structure under design state was calculated and analyzed, and the results were compared with actual axis pressure test results. It is proven that the method is feasible and can meet the requirements of structure bucking characteristics analysis.
