摘要
在回顾多点激励模态参数识别方法理论和应用的最新进展基础上,重点针对基于响应数据的多点激励参数识别法在模态参数识别中的应用进行了分析和总结。按对激励信号模型假设不同:基于白噪声的平稳随机激励假设和非平稳随机激励假设下多点激励模态参数识别技术分别进行深入的讨论。最后,对多点激励参数识别方法的发展前景进行了探讨和展望。
Multi-excitation modal analysis was used in large structures, such as, bridge, construction, aerospace industry. A survey of theory and application in modal parameter identification with multiple-excitation was presented based on response data. Then, a deep discussion on techniques of modal parameter identification with multi-excitation under different assumptions of excitation signal model： stationary random excitation and non-stationary random excitation was given. At last, the development prospect of measurement methods for parameter identification with muhiple-excitation was summarized.
