Structural optimization of a satellite interface: Performance assessment of commercial codes

Resumo

The performance assessment of commercial optimization codes was carried out for a satellite interface. The satellite interface consisting of a rectangular plate with reinforcements was used to connect the launcher to the satellite body, which enables to withstand loads transmitted by the launcher. Constraints were imposed in such way that longitudinal and transverse vibration modes do not couple with the launcher frequencies. The diversity of the optimization was found related to the different aspects of the interface design due to the objective-function, constrains and the choice of the design variables involved. The results indicate the potentiality of the optimization tools for the design of an aerospace structure.
