摘要
为了利用某一系统的输入和输出数据,快速、准确地提取该系统的模态参数,该文介绍了模态参数识别中最基本的一种方法,即分量分析法[2],提出了一种提高其模态参数识别精度的新算法。并且,举出一个实例证实了此方法的正确、可靠性。该算法最大优点是原理简单、易懂,方法容易实现,而且,可以不依赖人工操作,利用程序可以直接把需要的参数高精度地识别出来。
To identify the model parameters fast and accurately by using of the input and output of one system, this article introduces the most elementary method which is called part analysis,and gives a new arithmetic to improve the precision of model parameter identification. An example is provided to identify the model parameters by this way, the result verified the validity of this arithmetic. The virtue of this arithmetic is easy to understand and realize. We can get directly the wanted high precision model parameters identified by process without manual work.
