Orion Beam Datasets

The datasets provided by this repository comprise experimental data to investigate the nonlinear dynamic behavior of the Orion beam structure, which consists of two duraluminum beams assembled by bolted joints. To retain contact on a small area between both beams, this new lap-joint configuration proposes contact patches at each bolt connection. The Orion beam suggests an assembly configuration that associates bolts dedicated to “static” functions and to those to perform “damping” functions. This ensures a significant increase in the structural damping without degrading the structural stiffness. Experiments have been performed on the laboratory pôle Vibration and Acoustic, located at FEMTO-ST Institute, CNRS/UFC/ENSMM/UTBM, Department of Applied Mechanics, 24 chemin de l’Epitaphe, 25000 Besançon, France.
