چکیده:

When using different manufacturing processes, it is necessary to study and analyze the shape of the structures to determine their vibration behavior. In this paper, the dynamic behavior of two identical satellite structures, differing only in their lateral plates, manufactured by incremental forming and machining methods, have been analyzed, and compared using the FEM. This analysis allows for the qualification of design and manufacturing methods, without the actual performance of the expensive vibration tests. The analysis results show that the vibration behaviour of the formed satellite structure is better than that of the machined satellite structure. Results also show that due to the reduced weight of the formed satellite structure, the forming process has potential for cost reduction, and can be used as a replacement for the machining process.
