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…

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…

Scavenging Process Analysis in a 2-Stroke Engine by CFD Approach for a Parametric 0D Model Development

Stéphanie Cagin, Nachida Bourabaa, Eric Delacourt, Céline Morin, Xavier Fischer, Daniel Coutellier, Bertrand Carre, Sylvain Loumé

This paper presents a method to improve cylinder design of 2-stroke auto-ignition engine based on a CFD (Computational Fluid Dynamics) study of internal flows in the chamber and an unsteady global 0D parametric approach. In 2-stroke engine, scavenging process plays an important role regarding…

Variable and single neighbourhood diving for MIP feasibility

Jasmina Lazic, Raca Todosijević, Said Hanafi, Nenad Mladenovic

In this paper, we propose two new diving heuristics for finding a feasible solution for a mixed integer programming problem, called variable neighbourhood (VN) diving and single neighbourhood (SN) diving, respectively. They perform systematic hard variable fixing (i.e. diving) by exploiting the…

Failure stress criterion for adhesively bonded joint at different strain rates by using dynamic Arcan test device

Ludovic Dufour, Benjamin Bourel, Franck Lauro, Grégory Haugou, Nicolas Leconte, Nicolas Carrere

The purpose of this work is to determine the failure criterion evolution of assembly bonded with a strain rate dependent adhesive. A new modified ARCAN device is then designed to obtain the average stress at failure under different loading angles and for strain up to 350 s −1. Tests are performed…

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…
