Structural flexibility matrix generation method based on structural finite element model and related components

The invention discloses a structure flexibility matrix generation method and device based on a structure finite element model, equipment and a medium, and relates to the technical field of aerospace aircrafts, and the method comprises the steps: generating a structure finite element calculation grid based on a discrete element type, a discrete element size and discrete element distribution corresponding to a target part in a target aircraft, creating a structural finite element model of the target component; screening out surface grid points from the structural finite element model, and screening out a plurality of target surface grid points from the surface grid points to obtain a target grid point set; respectively acquiring displacement responses of all target surface grid points in the target grid point set under different preset degrees of freedom, and based on a preset degree of freedom sequence, assembling each displacement response to obtain a structural flexibility matrix of the target component; and
