摘要
该文对环境激励下结构模态参数识别的16种常用算法进行了概括综述。该文将模态参数识别算法分类为时域、频域两类,并针对算法流程进一步地将时域方法分为一步法与两步法。在分类的基础上,阐述了算法的适用条件与基本流程,对其中一些重要算法的理论与实现过程进行了详细地讨论。最后,对结构模态识别中的模态验证方法进行了简要地论述。
A summary and review of 16 commonly used algorithms for structure modal parameter identification under the ambient excitation is presented in this paper. After the classification of identification algorithms into time domain and frequency domain, the time domain algorithms are divided into the one-stage methods and two-stage methods ulteriorly based on the process of the algorithms. On the basis of the classification, the applicable condition and basic process of the identification algorithms are described, among which the principle and realizing process of several important algorithms are discussed in detail. The modal validation methods in the structure modal parameter identification are presented basically at the end of this paper.
