Sentence examples for modal identification is from inspiring English sources

A nonlinear modal identification is then performed.

Modal identification is performed using a Bayesian frequency domain method for asynchronous data and the global mode shape is assembled using the global least square method.

One important current focus of modal identification is a reformulation of modal parameter estimation algorithms into a single, consistent mathematical formulation with a corresponding set of definitions and unifying concepts.

In model updating, damage detection and structural health monitoring (SHM), modal identification is usually the first step to calculate the modal properties, such as natural frequencies, damping ratios and mode shapes, of the targeted structure utilizing the measured time-domain responses.

Given this essentially linear response, a modal identification is performed up to 3 kHz by means of a novel high resolution modal analysis technique [K. Ege, X. Boutillon, B. David, High-resolution modal analysis, Journal of Sound and Vibration 325 (4–5) (2009) 852 869].

The proposed method is validated by laboratory experiments where output-only modal identification is conducted on temporally-aliased acceleration responses and particularly the temporally-aliased video measurements of bench-scale structures, including a three-story building structure and a cantilever beam.

Two examples of modal identification are presented to demonstrate the availability and effectiveness of the proposed VBARX method.

Due to the special feature of the structure, field vibration tests and further modal identification were performed to investigate its dynamic performance.

Two examples of modal identification are carried out to demonstrate the availability and effectiveness of the proposed backward approach: (1) Numerical modal identification for a three-degree-of-freedom dynamic system with noise level in 20% of r.m.s of measured output data; (2) experimental modal identification of a cantilever beam.

Numerical results for complex modal identifications are presented, and the quality of the identified modal matrix and modal responses, extracted using the complex SOBI technique and implementing the proposed formulation, is assessed.

Therefore, to overcome these problems, a new combined method for modal parameter identification is proposed in this work.
