摘要
介绍AC500型飞机结构动力学有限元模型修正及其在MSCNastran的实现,修正结果表明,AC500修正模型的主模态计算结果与试验结果吻合性很好,满足工程精度要求,可以为AC500飞机的颤振适航分析提供可靠依据.
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.
