摘要：
It is difficult to measure the input forces of some operating structures. Only the operating response data can be used to identify modal parameters. A frequency domain poly-reference modal identification method under operational conditions was presented on the basis of the cross-correlation function of measured responses to solve the only-output problem. The proposed method in this paper was applied to an airplane model.
