Abstract Operational Modal Analysis allows to assess the modal model of rotating
machinery. However, it is needed to pre-process the measured vibration data such that the …

Safety-critical applications like the evaluation of aeroelastic stability during aircraft flight
require modal parameters identified with high accuracy. Promising methods of automated …

The estimation of modal parameters from a set of noisy measured data is a highly
judgmental task, with user expertise playing a significant role in distinguishing between …

A new modal parameter estimation method to directly establish modal models of structural
dynamic systems satisfying two physically motivated constraints will be presented. The …

Abstract The Wiener–Hammerstein (WH) model in discrete form is a cascaded connection of
three blocks including a linear dynamics block, a static nonlinearity block, and a (secondary) …

Assembling local mode shapes identified from multiple setups to form global mode shapes
is of practical importance when the degrees of freedom (dofs) of interest are measured …

Each operational modal analysis (OMA) technique may produce significant errors during the
identification procedure due to the applied methodology, environmental/operational …

In this study, an FRF based Bayesian approach is presented for modal identification of civil
structures with known seismic input. The proposed method utilizes the statistical properties …

This paper investigates the uncertainty propagation properties of a two-stage fast Bayesian
spectral density approach (two-stage fast BSDA) with separated modes proposed previously …

In the automotive industry, one of the most important comfort requirements in designing a
high quality vehicle is to avoid or minimize the noise in the passenger compartment …
