In the dynamical analysis of complex systems, running a detailed
high-resolution finite element model can be expensive, even for
obtaining the dynamic response at few frequency points. In this
paper, a new computational tool based on Bayesian emulators is
developed. Using this approach, the dynamic response over a
frequency range can be approximated using only a few response
values, obtained either from experimental measurements or by running
a finite element model at carefully selected input frequency points.
The proposed Bayesian emulator method is applied to two numerical
example problems and one problem with experimentally measured data.
It is shown that the method can be an effective predictive tool for
mid and high frequency vibration problems.
