Sentence examples for modal identification methods from inspiring English sources
Therefore, this method combines the advantages of the two existing modal identification methods and overcomes some of their limitations.
Existing BSS modal identification methods, however, require the number of sensors at least equal to that of sources (active modes).
In the existing modal identification methods for forced vibration, it is generally assumed that the forced vibration response dominates the measurement data and the influence of the ambient vibration response is ignored.
The main novelties of this work involve the new formulation in frequency-scale domain and the capacity for the identification of modal parameters without the step of ridges extraction in comparison with previous wavelet-based modal identification methods.
This paper proposes a new modal identification method of ambient vibration responses.
To overcome some of the limitations of the traditional modal identification method for a structure under ambient excitation, we propose a modal parameter identification method based on the Hankel matrix joint approximate diagonalization (HJAD) technique.
Significant conclusions about the complicated vibration processes composed of nonstationary and intrinsic modal terms are drawn by using the proposed empirical modeless decomposition and modal identification method.
Then the cross-correlation function is taken as the initial input signal to identify parameters with modal identification method in time domain.
However, the high-quality vibration data collection technology calls for a more accurate modal identification method to improve the accuracy of the results.
