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…

A mixed DG method for folded Naghdi's shell in Cartesian coordinates, Une méthode de Galerkin discontinue mixte pour une coque de Naghdi pliée en coordonnées cartésiennes

Serge Nicaise, Ismail Merabet

In this Note, a mixed formulation is proposed to solve Naghdi's equations for a thin linearly elastic shell. The unknowns of the problem are the displacement of the points of the middle surface, the rotation field of the normal vector to the middle surface of the shell and a Lagrange…, Dans cette Note, nous proposons une méthode mixte pour résoudre les équations du modèle de Naghdi de coques linéairement élastiques. Les inconnues du problème sont le déplacement des points de la surface moyenne, le vecteur de rotation de la normale à la surface moyenne et un multiplicateur de…

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…

Optimal control of magnetic fields in flow measurement

Serge Nicaise, Simon Stingelin, Fredi Tröltzsch

Optimal control problems are considered for transient magnetization processes arising from electromagnetic flow measurement. The magnetic fields are generated by an induction coil and are defined in 3D spatial domains that include electrically conducting and nonconducting regions. Taking the…
