Separation of the elastic waves’ system in pre-stretched bar devices

Grégory Haugou, Nicolas Leconte, Hervé Morvan

The loading mode generated by Kolsky bars apparatus is limited due to physical reasons to a duration time of around 0.4ms. This is not suited in the characterization of high ductility metallic alloys up to fracture at moderate strain rates, since the duration time is too short. The pre-stretched...

Friction Analysis in Bulk Metal Forming

Laurent Dubar, André Dubois, Mirentxu Dubar

A methodology to characterize friction according to the severe conditions of contact encountered in metal forming is presented. The main peculiarity of the proposed method is to use specimens and contactor made of industrial tool and workpiece surface in laboratory bench tests in order to ensure...

Experimental study of oil cooling systems for electric motors

Tanguy Davin, Julien Pellé, Souad Harmand, Robert Yu

The present study focuses on the use of lubricating oil as a coolant for electrical motors. Oil is introduced at each side of a 40 kW test machine to directly cool the stator coil end-windings. An experimental setup has been implemented to test different oil injection patterns. The influence of the...

Region of exponential stability of switched linear systems on time scales

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai

This paper deals with the stability analysis of a class of linear time-invariant switched systems on non-uniform time domains. The considered class consists of a set of linear continuous-time and linear discrete-time subsystems. Some sufficient and necessary conditions are derived to guarantee the...

Local versus global optimal sports techniques in a group of athletes

Aurore Huchez, Diane Haering, Patrice Holvoët, Franck Barbier, Mickael Begon

Various optimization algorithms have been used to achieve optimal control of sports movements. Nevertheless, no local or global optimization algorithm could be the most effective for solving all optimal control problems. This study aims at comparing local and global optimal solutions in a...
