ASPECTS OF THE INVESTIGATION OF THE DYNAMIC BEHAVIOUR OF MACHINE TOOLS BY OPERATIONAL MODAL ANALYSIS
Operational modal analysis (OMA) is an essential tool for understanding the structural dynamics of offshore wind turbines (OWTs). However, classical OMA algorithms require excitation structure to be stationary white noise, which often not case operational OWTs due presence periodic caused by rotor rotation. To address this issue, several solutions have been proposed in literature, including Kal...
Many transportation infrastructures all around the world are facing new challenges in terms of ageing and loss performance. The infrastructural asset managers required to perform scrupulous control health condition over time execute maintenance works. In this context, digital twin models should have a key role simplify speed up procedures for proper maintenance. This paper discusses advantages ...
On minimizing the influence of the noise tail of correlation functions in operational modal analysis
Automated operational modal analysis (OMA) is attractive and has been extensively used to replace traditional OMA, which requires much empirical observation engineers’ judgment. Still, the uncertainties on parameters spurious modes are challenging estimate under field conditions. For addressing this challenge, research proposed an automated identification approach. The approach consists of two ...
