A frequency domain blind identification method for operational modal analysis using a limited number of sensors
(Sage Publications Ltd, 2020-01-14)
Operational modal analysis is an experimental modal analysis approach, which uses vibration data collected when the structure is under operating conditions. Amongst the methods for operational modal analysis, blind source ...
Análise modal numérica de uma estrutura do tipo Baja
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia MecânicaUTFPR, 2019-07-04)
Modal analysis is the study of vibrations, more specifically about the dynamic properties of systems at the frequency domain. When projecting a structure in engineering, the modal analysis utilizes the total mass and ...
