| Abstract: | Based on MSC. NASTRAN software, a theory of super-element used in structure static analysis is deducted. The application procedure of the external super-element in civil aircraft structure analysis is proposed. The external super-element technology is adopted to deal with the finite element model of a pylon. Compared results show that, in static analysis the calculation results of external super-element are relatively consistent with those of the traditional calculation. Furthermore, about 97% of the computing time and 93% of the memory space are saved. |
