Abstract

Fretting wear is a very important phenomenon occurring in bladed disks. It causes that blades must be replaced in turbomachines during their life-cycle. Methods exist to predict fretting wear in quasistatic analysis. However they don't predict all the phenomena observed in blade attachments on real turbomachines. That's why this study assumes that dynamics plays a role in fretting wear. This paper is devoted to the realistic modelling and calculation of fretting wear and dynamical response of structures in unilateral contact with friction. Vibration and wear phenomena present very different scales both in time and space. Therefore the difficulty is in finding methods that enable one to solve the non-linear problem with a good compromise between the approximations made about the dynamical aspects and those linked with fretting-wear issues. Here, phenomenological examples are studied. They involve a small number of degrees of freedom with a view to understanding the complex coupling between vibration and fretting-wear. This way, they will show the relative importance of parameters.
