Dimension Optimization of a Carbon/Epoxy Lunch Vehicle Adaptor in Order to Maximize the First Resonance Frequency

One of the most important part of a lunch vehicles which were used to lunch satellites, is adaptor. This part is the interface between the rocket and satellite. So all the vibrations which caused by engine at lunch time are transmitted through this part and affect the satellite. Therefore the first resonant frequency of adaptor shall be higher than first three or four resonant frequency of the rocket. According to some studies, one of the newest type of adaptors is composite lattice structure. In order to design such an adaptor, a Fortran code was written as the input of Abaqus software. The frequency analyze is done by this software. On the other hand, Abaqus was linked to MATLAB software to find the optimum dimensions of all the parts of the adaptor. The results were much better than what was expected.
