Modal Analysis Of Damaged Structure By
Means Of Transform Of The Hilbert Type
Author(s)
J. Naprstek & S. Pospfsil
Abstract
The paper evaluates the characteristics of Fourier transform using the wave-
lets which are important for analysis of the frequency content of time pro-
cesses. Some shortcomings of these methods manifest themselves particu-
larly in the analysis of non-stationary processes and the processes produced
by non-linear systems. Their basic shortcoming, however, is their insuffi-
cient ability to describe local characteristics of the frequency content of the
process. As particularly the local changes of the dynamic characteristics
of the structure may be the sources of information on its state and extent
of damage, it is necessary to seek a procedure enabling to acquire detailed
knowledge of the frequency content of a time variable pro
