The development of more economical and safer societies requires to improve the means of transport and of energy production. Among these means, rotating machines hold a central place. To address these societal issues, it is then essential that the rotating machines technology be innovative and make progress on the following topics: performance, costs and noise reduction while continuing to maintain the components’ reliability, durability and safety. Thus, the purpose of this colloquium is to promote exchange in the rotor dynamic community around their most advanced research in coupling and nonlinear dynamic. Papers are solicited in all aspects of nonlinear dynamics or coupling in rotating machinery. The main objective is to have a state of the art in nonlinear numerical (or analytical) simulation (or analysis) tools applied in the field of rotating machinery associated or not with experiment. Concerning multi-physics coupling phenomena, it is mainly the aspects of stability and nonlinear behaviour which will be developed during this symposium. Applications with laboratory and field investigations are welcomed. The topics of interest include, but are not limited to, modal testing and identification, dynamic stability, nonlinear phenomena, parametric excitations, interactions (e.g., rotor-stator, torsion-bending, fluid-structure, and electromechanical), active and passive control techniques, disk assemblies, and case studies.
