Sentence examples for modal parameter based from inspiring English sources

This paper introduced a modal parameter based identification procedure to identify the equivalent system of structures under harmonic excitations.

The example of a steel stringer bridge model successfully illustrates that the proposed methods accurately identify structural macro strain modal shapes, and the results also reveals that macro strain based indexes are much more robust than traditional modal parameter based indexes for structural damage detection.

The procedure of identification of the instantaneous modal parameters based on the continuous wavelet transform (CWT) is given in detail.

Empirical equations are presented to evaluate modal parameters based on a parametric study using finite element analysis.

The identified modal parameters based on asynchronous data are evaluated by comparing with those identified based on synchronous data.

Previous research showed that, a complex quasi-modal parameter based system identification technique could be feasible for this purpose; however, the technique was only validated by identifying simple structures under harmonic excitation.

Vibrational measurement data are often nonstationary and modal parameter identification based on these data is of practical value for structural health monitoring and condition assessment.

The present identification method demonstrates its full effectiveness in detecting both flexible- and fixed-base modal parameters identified based on earthquake excitation, also in the presence of close modes and heavy damping (in terms of identification challenge).
