Transmitted torque observer applied to real time engine and clutch torque estimation

Rémi Losero, Jimmy Lauber, Thierry-Marie Guerra

In automation control system applications, the transmitted engine and clutch torque are unavoidable information for the control strategies. For example, these information are required to engine control, hybrid vehicle and automated transmission management. An angular domain discrete observer is…

A viscoelastic-viscoplastic model for short-fibre reinforced polymers with complex fibre orientations

Mariem Nciri, Delphine Notta-Cuvier, Franck Lauro, Fahmi Chaari, Bassem Zouari, Yamen Maalej

This paper presents an innovative approach for the modelling of viscous behaviour of short-fibre reinforced composites (SFRC) with complex distributions of fibre orientations and for a wide range of strain rates. As an alternative to more complex homogenisation methods, the model is based on an…

Thermal effect of the welding process on the dynamic behavior of the HSS constitutive materials of a fillet welded joint

Julien Carrier, Eric Markiewicz, Grégory Haugou, David Lebaillif, Nicolas Leconte, Hakim Naceur

Welded joints, due to their manufacturing process, are commonly weakened areas. This study analyses the dynamic behavior of the Base Metal (BM) and the Heat-Affected Zone (HAZ) of an HSS (High Strength Steel) fillet welded joint. Firstly, a specific approach has been developed to generate the HAZ…

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…

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…

Harmonized methodology for Safety Integrity Level allocation in a generic TCMS application

Kiswendsida Abel Ouedraogo, Julie Beugin, El Miloudi El Koursi, Joffrey Clarhaut, Dominique Renaux, Frédéric Lisiecki

This article presents a generic methodology for SIL allocation to railway rolling stock safety-related func-tions to solve the SIL concept application issues. This methodology is based on the flowchart formalism al-ready used in CSM European regulation. It starts with the use of quantitative safety…

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…
