Abstract
Problem Statement (Relevance). Large-sized monolithic machined panels are one of the most complicated elements in the plane design. A set of large overall dimensions and variable camber of low rigidity determine difficulties with manufacturing such parts. As it is required to achieve high accuracy of the shape of such panels, their manufacturing process is also complicated by structural features, namely thin walls, stiffening ribs and low camber, to whose achievement total deformation should be proportional to an elastic component. The results of the panel geometry generation depend on many interdependent factors, which, in their turn, influence the stress and strain state and shape of parts. One of promising methods of manufacturing such parts is a method of fitting of ribs. This process is widely used for the geometry generation of sections and beams. Now, available methods for calculating mode parameters of fitting ribs of monolithic parts are not enough covered in publications. Objective. The research is aimed at improving procedures for calculating mode parameters of metal treatment by local plastic deformation methods. Methods Applied. Finite element modeling of a local plastic deformation process using the example of fitting of panel ribs. Originality. A concept of simulation of the geometry generation of monolithic machined panels by a fitting method. Practical Relevance. The developed finite element model represents input data for calculating mode parameters of the process of fitting ribs of monolithic machined panels. Results. The authors developed a procedure for building and analyzing the finite element model to determine internal force factors, occurring in monolithic machined panels during their fitting.
