| Abstract: | The GARTEUR aircraft model is analyzed using the Nastran software to gain the intrinsic frequency and mode shape. Based on the rational fraction model of frequency response function, Forsythe orthogonal polynomial is utilized to improve the numerical condition. Starting from the experiment data of FRF, a program is compiled to calculate further the modal parameters of this model. In the end, validity and practicability of the software are validated. |
