基于频域重构的激励和响应识别方法
|
摘要
本文提出了一种基于频域重构的激励和响应识别方法,由两组试验获取的激励信号在频域上重新构造出一种新的激励,以新的激励去识别响应信号,从而获取试验中较难实现的激励和响应信号,该方法已成功应用于实际工程试验分析中。
In this paper, an excitation and response identification method based on frequency domain reconstruction is proposed. The excitation signals obtained by the two experimental groups in the requency domain construct a new excitation, with the new excitation to identify the response signal, and gets more difficult to achieve in the test of the excitation and response signals. This method has been successfully applied to the analysis of the actual engineering test.
