Génération de trajectoires en fabrication additive par projection de poudre pour contrôler la géométrie et la microstructure

La fabrication additive est devenue un procédé très répandu ces dernières années en raison de sa capacité à produire des pièces de formes complexes. Cependant, malgré son utilisation généralisée, le contrôle des propriétés mécaniques des pièces…

Modélisation et Évaluation Analytique du Temps de Réponse des Systèmes de Contrôle-Commande Distribués en utilisant des Réseaux de Petri et l'Algèbre des Dioïdes

The problem addressed in this thesis concerns above all the analytical evaluation of a response time bound for a distributed control system, in a critical industrial context. The teleology of the work is therefore to prove this bound by a method…

Combining Model-based and Data-based approaches for online predictions of human trajectories

Accurately predicting human movement trajectories is of critical interest in multiple fields, including humanexoskeleton interaction. In general, such predictions can be obtained from model-based approaches (e.g., optimal control theory) or from…

A methodology for weld bead geometry and operating conditions determination in Wire Arc Additive Manufacturing

When manufacturing a part using Directed Energy Deposition (DED) pro-cesses such as Wire Arc Additive Manufacturing (WAAM), it is necessary to determine the deposition path and operating parameters (wire feed speed, torch speed, energy). While the…

L-PBF AM process failures causal chain: an FMEA-based monitoring approach for process control

The laser powder bed fusion (L-PBF) additive manufacturing process offers many advantages. How- ever, its industrial integration still needs to be improved due to the certification constraints of the produced parts. Thus, this paper proposes a…

Human movement modifications induced by different levels of transparency of an active upper limb exoskeleton

Active upper limb exoskeletons are a potentially powerful tool for neuromotor rehabilitation. This potential depends on several basic control modes, one of them being transparency . In this control mode, the exoskeleton must follow the human…

Modal approach based on global stereocorrelation for defects measurement in wire-laser additive manufacturing

Producing near net shape parts with complex geometries using wire-laser additive manufacturing (AM) often requires a mastered and optimized process. Differences between the constructed and nominal geometries of the manufactured entities demand an in…
