    • NON-LINEAR OBSERVER-BASED CONTROL OF FLEXIBLE-JOINT MANIPULATORS USED IN MACHINE PROCESSING 
      Communication avec acte
      QIN, Jinna; LEONARD, François; ABBA, Gabriel (ASME, 2012)
      This paper proposes to use a non-linear observer to build the state and the external force of flexible manipulator robots during their machining (composite materials) processes or Friction Stir Welding (FSW) processes. ...
    • Influence of frictions on gait optimization of a biped robot with an anthropomorphic knee 
      Communication avec acte
      HOBON, Mathieu; LAKBAKBI EL YAAQOUBI, Nafissa; ABBA, Gabriel (IEEE, 2013)
      This paper presents the energy consumption of a biped robot with a new modelled structure of knees which is called rolling knee (RK). The dynamic model, the actuators and the friction coefficients of the gear box are known. ...
    • Some approaches on industrialization of steel thixoforging processes 
      Communication avec acte
      ccBECKER, Eric; ccLANGLOIS, Laurent (Trans Tech Publications, 2012)
      Based on several years of research, this paper presents some approaches on industrializing steel thixoforging processes. From a billet to a complex-shaped final part obtained in one single step, several key elements of the ...
    • Thixoforming of Steel: New Tools Conception to Analyse Thermal Exchanges and Strain Rate Effects 
      Communication avec acte
      CEZARD, Pierre; ccBECKER, Eric; MATHIEU, Stéphane; PIERRET, Jean-Christophe; RASSILI, Ahmed (E. Cueto and F. Chinesta, 2007)
      Through different papers [1,2], authors shown that the influence of thermal exchanges was a first order parameter on the semi-solid steel behaviour, and certainly for every semi-solid metallic materials. These thermal ...
    • INFLUENCE OF EXPERIMENTAL CONDITIONS ON MATERIAL RESPONSE DURING THIXOEXTRUSION PROCESS 
      Article dans une revue avec comité de lecture
      NEAG, Adriana; ccBECKER, Eric; POP, Mariana; HENRION, Emerik (Technical University of Cluj-Napoca, 2011)
      The behavior of aluminum alloy to deformation is strongly influenced by the morphology of the microstructure. This paper illustrates several experimental research activities for thixoextrusion of 7075 aluminum alloy being ...
    • Evaluation of process causes and influences of residual stress on gear distortion 
      Article dans une revue avec comité de lecture
      HUSSON, Rémi; SILVANI, Serge; SCHEER, Thomas; ccBAUDOUIN, Cyrille; ccDANTAN, Jean-Yves (Elsevier, 2012)
      In the automotive industry, heat treatment of components is implicitly related to distortion. This phenomenon is particularly obvious in the case of gears because of their typical and precise geometry. Even if distortion ...
    • A generic methodology to improve the control of forging process parameters 
      Article dans une revue avec comité de lecture
      ALLAM, Zakaria; ccBECKER, Eric; KRUMPIPE, Pierre; ccBAUDOUIN, Cyrille; ccBIGOT, Regis (Trans Tech Publications, 2013)
      One of the common problems in forging processes is the lack of key process parameters control, as well as their identification. Certain controlled parameters exist, such as temperature or stroke length, which are usually ...
