| Abstract: | The dynamic finite element model updating of AC500 airplane and the application of MSC Nastran is introduced. The updated results indicate that the computing main mode parameter modified model of AC500 matches very well with the test results. It provides a credible proof for the flutter analysis of AC500. |
