Specialized Reduced Models of Dynamic Flows in 2-Stroke Engines

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

The complexity of scavenging by ports and its impact on engine efficiency create the need to understand and to model it as realistically as possible. However, there are few empirical scavenging models and these are highly specialized. In a design optimization process, they appear very restricted…

Dynamic recrystallization observed at the tool/chip interface in machining

Yannick Senecaut, Michel Watremez, Julien Brocail, Laurence Fouilland-Paille, Laurent Dubar

In numerical approaches for high speed machining, the rheological behavior of machined materials is usually described by a Johnson Cook law. However, studies have shown that dynamic recrystallization phenomena appear during machining in the tool/chip interface. The Johnson Cook constitutive law…

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…

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…
