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.
