Abstract

A procedure for the automatic modal identification based on Narrow-Band algorithms is presented in this paper. The Lagrange interpolation polynomial is firstly utilized to find the modal peaks automatically. Then the modal assurance criterion values between adjacent modal vectors are calculated to decide the fitting band automatically. The procedure can be applied to Narrow-Band algorithms both for experimental and operational modal analysis. The result of automatic identification of real life testing and experimental data is finally demonstrated.
