Abstract

Relevance. Forming of long panels is one of the most complex technological processes in aircraft manufacturing. A conventional approach to forming involves press bending methods in combination with shot peening of aerodynamic surfaces. An alternative approach is the use of combined forming technology developed by Irkutsk National Research Technical University, when the resulting shape is generated by superimposing a ruled surface, formed by deforming the edges with rollers or pressing, and a double curved surface formed by shot peening of the aerodynamic surface of a part. To date, the combined forming technology has been tested in production. There is special equipment and methodologies for calculating the process parameters. However, to transfer to a program control mode, we should solve several issues related to assigning the shot peening process parameters, taking into account the design features of the part. Objective. To improve accuracy of calculating the shot peening process parameters in the combined technological process of forming long panels based on the analysis of their geometric parameters. Methods Applied. Automated programming was applied in the three-dimensional modeling of large-sized parts with complex shapes. Originality. A methodology for the automated calculation of geometric parameters for long panels was proposed to calculate the process parameters for combined forming of parts. Results. The authors developed the methodology for an automated analysis of geometric parameters of parts; created software to calculate the moment of inertia, equivalent rectangular section thickness, and radius of curvature of the surface the part sections, representing the initial data for calculating the processing modes. Practical Relevance. The developed methodology ensures improved accuracy and reduced labor intensity of calculating the process parameters for forming the aircraft panel parts and solves a set of tasks aimed at increasing efficiency of manufacturing the long panels.
