Qualitative Analysis of Forced Response of Blisks With Friction Ring Dampers
Denis Laxalde, Fabrice Thouverez, Jean-Jacques Sinou +1
A damping strategy for blisks (integrally bladed disks) of turbomachinery involving a friction ring is investigated. These rings, located in grooves underside the wheel of the blis…
The influence of cracks in rotating shafts
Jean-Jacques Sinou, A. W. Lees
In this paper, the influence of transverse cracks in a rotating shaft is analysed. The paper addresses the two distinct issues of the changes in modal properties and the influence…
Non-linear dynamic of rotor-stator system with non-linear bearing clearance
Jean-Jacques Sinou, Fabrice Thouverez
The study deals with a rotor-stator contact inducing vibration in rotating machinery. A numerical rotor-stator system, including a non-linear bearing with Hertz contact and clearan…
The influence of crack-imbalance orientation and orbital evolution for an extended cracked Jeffcott rotor
Julio Gomez-Mancilla, Jean-Jacques Sinou, V. R. Nosov +2
Vibration peaks occurring at rational fractions of the fundamental rotating critical speed, here named Local Resonances, facilitate cracked shaft detection during machine shut-down…
Anisotropic behaviour law for sheets used in stamping: A comparative study of steel and aluminium
Jean-Jacques Sinou, Bruno Macquaire
For a car manufacturer, reducing the weight of vehicles is an obvious aim. Replacing steel by aluminium moves towards that goal. Unfortunately, aluminium's stamping numerical simul…
