An Alternative Method to the Identification of the Modal Damping Factor based on the Dissipated Energy
Montalvão, Diogo; Silva, J. M. M. (2015-03-01)The identification of the modal parameters from frequency response functions is a subject that is not new. However, the starting point often comes from the equations that govern the dynamic motion. In this paper, a novel ... -
A Contribution to the Modal Identification of the Damping Factor based on the Dissipated Energy
Montalvão, Diogo; Silva, J. M. M. (European Association for Structural Dynamics (EASD), 2014-07)ABSTRACT: The identification of the modal parameters from frequency response functions is a subject that is not new. However, the starting point often comes from the equations that govern the dynamic motion. In this paper, ... -
Estimation of the rotational terms of the dynamic response matrix
Montalvao, D; Ribeiro, A. M. R.; Maia, N. M. M.; Silva, J. M. M. (2004)The dynamic response of a structure can be described by both its translational and rotational receptances. The latter ones are frequently not considered because of the difficulties in applying a pure moment excitation or ... -
On the estimation of rotational frequency response functions
Montalvao, D.; Ribeiro, A. M. R.; Maia, N. M. M.; Silva, J. M. M. (KATHOLIEKE UNIV LEUVEN, DEPT WERKTUIGKUNDE, 2005)Rotational receptances can perform an important role when predicting the dynamic behaviour both in theoretical and experimental models, especially when a modification includes a rotational inertia or a rotational stiffness. ...
