Sentence examples for modal identification process from inspiring English sources

Even if a number of applications have shown that OMA works also when the input spectrum is smooth enough, if this assumption is not fulfilled, the modal identification process may become more complex or even fail due to dominant frequency components of the input appearing in response spectra.

The challenges of accurately identifying the dynamic characteristics of bridge structures from ambient vibration responses persist because, unlike in the ideal laboratory environment, elevated levels of noise in data are unavoidable at any in-situ testing site and may have detrimental effects on the modal parameter identification process and results.

Based on this advantage, strain modal identification by processing the dynamic macro strain measurement is investigated.

For cases in which large modal truncation errors (or modeling errors) exist, the identification process also becomes unidentifiable.

Discussions on the relative accuracy of identified natural frequency and mode shape and their relative significance in the model updating process have been made via processing the vibration data through the Fast Bayesian FFT modal identification method.

A distributing process is proposed for Random Decrement Technique (RDT), to accurate modal identification.

The automation of the eigenvalue selection process would provide a lot of advantages for modal identification.

The proposed generalized total least-squares (GTLS) algorithm provides an accurate modal parameter estimation by the integration of this noise model in the parametric identification process.

The modal parameters derived from the measured linear and nonlinear Frequency Response Functions (FRF) of the bonded structure are used in identification process.

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.
