Analysis of the sensitivity of a vibration-based procedure for structural identification
We analyze the accuracy of estimation of structural component material properties (elastic modulus, Poisson’s ratio, density, etc.) using the technique for measuring the eigen frequencies of oscillations. The accuracy of frequency estimation using the Fourier method and its influence on the fi...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We analyze the accuracy of estimation of structural
component material properties (elastic
modulus, Poisson’s ratio, density, etc.) using
the technique for measuring the eigen frequencies
of oscillations. The accuracy of frequency
estimation using the Fourier method and its influence
on the final result are evaluated. Relationships
between the errors in the frequency
estimation and those in the identified parameters
are derived using the meta-model method.
Application of the method is illustrated by the
example of a shell element with a stiffening rib. |
