Résumé / Abstract

The following paper focuses on same-sign stiffness cross coupling from several viewpoints. First, the influence on rotordynamics is analyzed and discussed, followed by a discussion of how past experiments measuring cross-coupled forces on rotating components may have been in error due to an incomplete testing procedure. Finally, experimental tests are presented on a partitioned damper seal and the correct and complete experimental procedure for determining cross-coupled coefficients is described.
