以导弹动力学模型修正为研究背景，建立基于结构试验振型数据的具有多阶振型面积要求的动态修正设计方法，通过导弹模型动力学修正实例，证明提出的基于振型面积差最小的结构动态修正设计方法在工程实际问题中合理可行，修正后的模型在试验频率、振型数据方面具有较高的相符度，实现模型参数的有效修正。

A dynamic model updating design method based on structural experimental modal data is established to meet the requirements of multi-step mode shape areas under background of missile dynamic model updating. The feasibility of the method is proved through an engineering example of a missile dynamic model. The results of frequency and mode shape show good agreement between experimental and updating modal. It reveals that the method is effective to solve model parameter updating problems.
