Modeling Damping in Mechanical Engineering Structures


Prof. Michel Lalanne

INSA-Lyon Scientific and Technical University, France


Abstract


During the design of engineering structures, numerical models are used to ensure satisfactory dynamic behavior. Natural frequencies, modes, frequency and time responses, are dependent on damping which can be quite difficult to model. This conference presents some mechanical engineering structures studied at Laboratoire de Mecanique des Structures whose damping was due to concentrated element, to distributed elements or to several simultaneous effects and discusses methods employed to take into account damping. Applications shown are mostly in the field of machinery dynamics.
