Influence of Axial Thrust Bearing on the Dynamic Behavior of an Elastic Shaft : Coupling between the Axial Dynamic Behavior and the Bending Vibrations of a Flexible Shaft
Journal of Vibration and Acoustics, 2001Co-Authors: Sébastien Berger, Olivier Bonneau, Jean FreneAbstract:This paper presents the nonlinear Dynamic Behavior of a flexible shaft. The shaft is mounted in two journal bearings and the axial load is supported by a hydroDynamic thrust bearing. The coupling between the axial thrust bearing Behavior and the bending vibrations of the shaft is studied in particular. The shaft is modeled with typical beam finite elements. The Dynamic Behaviors of the fluid supports are considered as nonlinear. The Dynamic Behavior is analyzed using an unsteady time integration procedure. The paper shows the coupling between the axial Dynamic Behavior and the bending vibrations of the shaft.

Influence of Axial Thrust Bearing Defects on the Dynamic Behavior of an Elastic Shaft
Tribology International, 2000Co-Authors: Sébastien Berger, Olivier Bonneau, Jean FreneAbstract:In this work, the non-linear Dynamic Behavior of a flexible shaft is presented. The shaft is mounted in two journal bearings and axial load is supported by a hydroDynamic thrust bearing, at one end. The coupling between the axial thrust bearing Behavior and the bending vibrations of the shaft is especially studied. The shaft is modeled by a typical beam finite element method and includes gyroscopic effects. The Dynamic Behavior of the journal bearings and the thrust bearing are considered to be non-linear. The Dynamic Behavior is analyzed with a transient time integration procedure. The thrust bearing provides additional stiffness and additional damping on the flexible shaft. A defect on the thrust bearing rotor excites a critical speed.

Dynamic Behavior of two span continuous concrete bridges under moving high speed train
Computers & Structures, 2004Co-Authors: Jongwon Kwark, E S Choi, Y J Kim, Byungsuk Kim, S I KimAbstract:Abstract Experimental and theoretical studies have been performed to determine the Dynamic Behavior of bridges crossed by the Korean high-speed train (KHST). Through this study, significantly amplified Dynamic responses compared to static responses of the bridge crossed by trains running at speed close to the critical speed have been obtained. The numerical method technique presented in this study shows reasonable results concerning the Dynamic Behavior analysis of bridges under trains running at high-speed. In the case of the KHST, train–bridge interaction effects related to the Dynamic response of the bridge appeared to be significant at every speed.
