Etude des caractéristiques dynamiques des impacts obliques et de l'usure associée

Abstract : Vibrations of the steam generator (SG) tubes in nuclear power plants induce impacts between the tubes and antivibration bars (AVB). As a consequence, wear is generated. A test rig is designed and used to perform impacts between a SG tube sample and an AVB sample with various incidence angles. Normal and tangential velocities before and after an impact as well as the normal and tangential components of the contact load are measured during the tests. The dynamic characteristics of the impacts are studied and related to generated wear.
