Abstract
In the article the authors present a method of restrained elastomer bending of aircraft sheet parts with curved sides. Manufacturing of a part is carried out in two transitions; as a result of the first transition a part with thinning in the radial part is obtained, the second transition is carried out on the mold block of reduced height, as a result of which the resulting wave of excess material deforms along the radius of the bending mandrel. In the finished part, we can observe an increase in the thickness of the workpiece in the zone of the bend radius. Numerical studies of the process were conducted using the ANSYS/LS-DYNA software complex. As part of the study, the process flow model was worked out, the distribution of thickness of the material of the part over the entire surface under consideration was obtained, and graphs were plotted showing the elastomer pressure distributions and the deformation of the material of the part at characteristic points.
