Vibrations are the root cause of many mechanical and civil structure failures. Dynamic
characteristics of a structure must be extracted to better understand structural vibrational …

To increase the contribution of offshore wind energy to the global energy mix in an
economically sustainable manner, it is required to reduce the costs associated with the …

Operational modal analysis (OMA) is used to identify the modal parameters of a structure
under operational conditions, which reflects the real boundary conditions and state …

We present a novel approach to harmonic disturbance removal in single-channel wind
turbine acceleration data by means of time-variant signal modeling. Harmonics are …

The dynamics of a milling robot have a significant impact on machining efficiency and
quality. Traditional experimental modal analysis (EMA) is used to study the dynamics of …

Experimental modal analysis is challenging when the component has a highly three-
dimensional shape, since a great number of measurement points are needed with accurate …

In most output-only-based modal identification methods, the excitation and the measurement
error are assumed to be white Gaussian noise. One of the obstacles appears once the …

Abstract The transmissibility-based Operational Modal Analysis (OMA) technique has
attracted substantial research interest over the past two decades due to its capability to …

A full-scale short-span cable-stayed bridge on a wind-exposed hill in New South Wales in
Australia, was instrumented to assess its dynamic response to ambient vibration. The …

Modal parameter identification can be a valuable tool in mechanical engineering to predict
vibrational behaviour and avoid machine damage during operation. Operational modal …
