Friction coefficients in cold forging: A global perspective

Peter Groche, Philipp Kramer, Niels Bay, Peter Christiansen, Laurent Dubar, K. Hayakawa, Chengliang Hu, K. Kitamura, Philippe Moreau

Worldwide, at least twenty different tribological tests have been proposed for the empirical determination of friction coefficients in cold forging processes. Due to the varying test setups, means of measurement, and level of abstraction, the comparability of the outcomes is, however, disputable.…

Experimental study of the mechanical strength and the failure of multi-sheet, multi-material spot-welded assemblies under pure and combined loading conditions

Rim Chtourou, Fahmi Chaari, Grégory Haugou, Nicolas Leconte, Eric Markiewicz, Bassem Zouari

Resistance Spot Welding (RSW) is widely used in the automotive industry thanks to its production convenience and cost effectiveness. Around four thousands spot welds are indeed employed to assemble the body-in-white. RSW of multiple sheets and combining multiple materials are increasingly realized…

An Analysis of Electroplated cBN Grinding Wheel Wear and Conditioning during Creep Feed Grinding of Aeronautical Alloys

Gorka Vidal Irusta, Naiara Ortega, Héctor Bravo, Mirentxu Dubar, Haizea González

Cubic boron nitride (cBN), in addition to diamond, is one of the two superabrasives most commonly used for grinding hard materials such as ceramics or difficult-to-cut metal alloys such as nickel-based aeronautical alloys. In the manufacturing process of turbine parts, electroplated cBN wheels are…

Time temperature equivalence for a mineral filled polymer for automotive applications

Vincent Dorleans, Franck Lauro, Rémi Delille, Sylvain Treutenaere, Delphine Notta-Cuvier, Bruno Bennani, Grégory Haugou, Benjamin Bourel, Éric Michau, Jean-David Thoby

Polymers are currently used in several industrial applications such as the interior components of the vehicle. We find them for example in the design of dashboards or door panels. These materials may be subjected to different types of load like the temperature variation or high strain rates due to…

Reactive Power Dispatch Optimization with Voltage Profile Improvement Using an Efficient Hybrid Algorithm

Zahir Sahli, Abdelatif Hamouda, Abdelghani Bekrar, Damien Trentesaux

This paper presents an efficient approach for solving the optimal reactive power dispatch problem. It is a non-linear constrained optimization problem where two distinct objective functions are considered. The proposed approach is based on the hybridization of the particle swarm optimization method…

Sliding-Mode-Based Observer–Controller Structure for Fault-Resilient Control in DC Servomotors

Suneel Kumar Kommuri, Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu

This paper presents a robust observer-controller scheme for sensor fault-resilient control in dc servomotor drive-based applications (such as antennae control for satellite tracking, radio telescopes, and conveyor belt systems). In contrast to the earlier works on abrupt faults, this paper…

Effect of robotic-assisted gait rehabilitation on dynamic equilibrium control in the gait of children with cerebral palsy

Laura Wallard, Gilles Dietrich, Y. Kerlirzin, Jonathan Bredin

Due to the intensity and repetition of movement, roboticassisted gait training therapy could have a beneficial effect on the recovery and improvement of postural and locomotor functions of the patient. This study sought to highlight the effects of robotic-assisted gait rehabilitation in gait of…

Two-dimensional heat transfer coefficients with simultaneous flow visualisations during two-phase flow boiling in a PDMS microchannel

Sofia Korniliou, Coinneach Mackenzie-Dover, John R.E. Christy, Souad Harmand, Anthony J. Walton, Khellil Sefiane

Infrared (IR) thermography was combined with simultaneous high speed flow visualisation and pressure measurements from integrated pressure sensors inside the microchannel, in order to produce two-dimensional (2D) high spatial and temporal resolution two-phase heat transfer coefficient (HTC) maps…

Hybrid control design for limit cycle stabilisation of planar switched systems

Mohammed Benmiloud, Atallah Benalia, Mohamed Djemai, Michael Defoort

This paper addresses the control problem of an important class of hybrid dynamical systems where the desired state does not belong to the set of subsystem equilibria. Beyond the practical stabilisation where the system trajectory has to be driven to a neighbourhood of a desired state, a control law…

Performance indicators nomenclatures for decision making in sustainable conditions based maintenance

Olivier Sénéchal

The maintenance activity is by nature an important lever for action on the sustainability of production systems. To implement new performance indicators in this perspective involves to use data, information, and knowledge missing in the traditional maintenance environments, or at least not…
