Résumé :

An innovative magnetostatic force sensor consisting of a laser source, a tiny cantilever beam, and a small permanent magnet was developed and used for defect inspection in ferromagnetic samples in the present article. The penetrating zone within a ferromagnetic material under the magnetic field provided by a permanent magnet was called the magnetic sensing zone (MSZ), and surface or internal defects within the MSZ were inspected by measuring the change in the magnetostatic force. This magnetostatic force could be calculated by the Maxwell tensor integrating over the surface and interface of a ferromagnetic material. Numerical and experimental results demonstrated that this sensor was reliable and could precisely inspect the defects of different sizes in ferromagnetic samples. In summary, the sensor proposed in this paper has the potential for industrial applications to detect surface and sub-surface tiny defects on ferromagnetic steel thin sheets, such as the zinc slag defect of hot galvanized sheets, cracks on cold-rolled sheets, and the ferromagnetic oscillation marks of continuous casting.

Résumé :

Abstract The paper presents the measurement method and results as well as the results of comparative calculations aimed at determination of material data for the package of ferromagnetic sheets insulated with epoxy lacquer. During the test, the package of sheets was treated as a 3D orthotropic material. The values of Young’s and Kirchhoff’s moduli for a pre-compressed package of sheets, in accordance with the used manufacturing technology of the medium and high power electric motors’ rotors, were detennined. The carried out FEM comparative calculations confirmed that the determined mechanical parameters of the package of sheets as a 3D orthotropic material, i.e. Young’s and Kirchhoff’s moduli, for the compressive stress range of 1.0÷2.5 MPa, are included in the linear range. It was assumed that the determined mechanical properties of the package of sheets are necessary at the design stage for FEM simulation calculations of the electric motors’ vibration and strength properties. As a result of the tests, it was found that they should be repeated in order to determine the properties of other sheets or those coated with different insulating lacquer.

Résumé :

Due to the particular arrangement of permanent magnets, a Halbach array has an significant effect of magnetism and magnetic self-shielding. It can stretch the magnetic lines on one side of the magnetic field to obtain an ideal sinusoidal unilateral magnetic field. It has a wide application range in the field of energy harvesting. In practical applications, magnetic induction intensity of each point in magnetic field is not only related to the induced current and conductor but also related to the permeability of the medium (also known as a magnetic medium) in the magnetic field. Permeability is the physical quantity that represents the magnetism of the magnetic medium, which indicates the resistance of magnetic flux or the ability of magnetic lines to be connected in the magnetic field after coil flows through current in space or in the core space. When the permeability is much greater than one, it is a ferromagnetic material. Adding a ferromagnetic material in a magnetic field can increase the magnetic induction intensity B. Iron sheet is a good magnetic material, and it is easy to magnetize to generate an additional magnetic field to strengthen the original magnetic field, and it is easy to obtain at low cost. In this paper, in order to explore the influence of ferromagnetic material on the magnetic field and energy harvesting efficiency of the Halbach array energy harvesting structure, iron sheets are installed on the periphery of the Halbach array rotor. Iron sheet has excellent magnetic permeability. Through simulation, angle between iron sheet and Halbach array, radian size of iron sheet itself and distance between iron sheet and Halbach array can all have different effects on the magnetic field of the Halbach array. It shows that adding iron sheets as a magnetic medium could indeed change the magnetic field distribution of the Halbach array and increase energy harvesting efficiency. In this paper, a Halbach array can be used to provide electrical power for passive wireless low-power devices.

Résumé :

Abstract Superconductivity (SC) and ferromagnetism (FM) are normally antagonistic, and their coexistence in a single crystalline material appears to be very rare. Over a decade ago, the iron-based pnictides of doped EuFe2As2 were found to render such a coexistence, primarily because of the Fe–3d multi-orbitals which simultaneously satisfy the superconducting pairing and the ferromagnetic exchange interaction among Eu local spins. In 2016, the discovery of the iron-based superconductors AEuFe4As4 (A = Rb, Cs) provided an additional and complementary material basis for the study of the coexistence and the interplay between SC and FM. The two sibling compounds, which can be viewed as an intergrowth or a hybrid between AFe2As2 and EuFe2As2, show SC in the FeAs bilayers at T c = 35–37 K and magnetic ordering at T m ∼ 15 K in the sandwiched Eu2+-ion sheets. Below T m, the Eu2+ spins align ferromagnetically within each Eu plane, making the system as a natural atomic-thick superconductor–ferromagnet superlattice. This paper reviews the main research progress in the emerging topic during the past five years. An outlook for the future research opportunities is also presented.

Résumé :

Induction heating or welding can be performed by considering the combined effect of ferromagnetic heating due to magnetic hysteresis losses and eddy current heating due to conductive material. Nonconducting thermoplastic composite parts can be joined or welded by induction heating using a susceptor sheet filled with nickel-coated carbon fibers (NiCCFs) and nickel-coated graphite particles (NiCGPs) or both with polypropylene (PP) thermoplastic matrix. Above the percolation threshold, NiCCFs can serve as conductive materials and nickel coating will provide the ferromagnetic heating. NiCCF/PP and NiCCF/NiCGP/PP susceptor sheets were developed via melt mixing using a twin-screw extruder and sheets were produced by Calendering process. Induction heating tests were performed on a circular pancake coil and at frequencies below 1 MHz. In induction heating, fiber heating by Joule loss, junction heating (i.e. dielectric heating and contact resistance heating), as well as magnetic hysteresis effect were observed in both the cases. Heating in hybrid filler was higher at lower filler concentrations; however, with higher concentrations, heating reduced. Reduction in induction heating maybe due to a reduction in electrical conductivity was observed. Electrical conductivity was measured in fibers direction by a Keithley electrometer using a four-point measuring method and temperature was measured by an infrared thermal camera. Microstructure characterization was performed by X-ray computed microtomography and light microscopy.

Résumé :

Les machines électriques de forte puissance sont soumises à des contraintes mécaniques, thermiques et magnétiques sévères en fonctionnement. Pour assurer leur fiabilité et la continuité de leur opération, il est crucial de disposer d'informations en temps réel sur ces contraintes, souvent à l'échelle locale. Les technologies de capteurs sans fil et sans batterie, combinées à des techniques efficaces d'analyse des données et de traitement des signaux, sont indispensables pour répondre à ce besoin. Les ondes acoustiques de surface permettent de concevoir des capteurs sans fil et totalement passifs, capables de mesurer de nombreuses grandeurs physiques telles que la température, les contraintes mécaniques et le champ magnétique, grâce à une ingénierie avancée du design. Le travail réalisé dans cette thèse a permis de développer des capteurs SAW multi-grandeurs pour la mesure des déformations, de la température et du champ magnétique. Ces capteurs ont d'abord été calibrés sur des bancs d'essais en laboratoire, puis utilisés pour caractériser les propriétés mécaniques, telles que la magnétostriction, et les propriétés magnétiques, telles que les pertes magnétiques, des tôles ferromagnétiques employées dans la conception des machines électriques de forte puissance. La caractérisation des propriétés des tôles ferromagnétiques est cruciale pour plusieurs raisons : concevoir des systèmes électromagnétiques efficaces, minimiser les vibrations et les bruits indésirables, contrôler la dissipation d'énergie, prévenir la fatigue des matériaux, optimiser la conception des composants pour l'efficacité énergétique et développer des composants résistants à la chaleur pour la fiabilité et la durabilité... Le projet de thèse implique l'entreprise JEUMONT Electric (société de haute technologie spécialisée dans les solutions de conversion d'énergie), le groupe AIMAN-FILMS de l’IEMN et l'équipe Outils et Méthodes Numériques du L2EP. Chaque partenaire apporte des compétences spécifiques pour aborder l'instrumentation multi-physique des machines électriques de forte puissance
High-power electrical machines are subjected to severe mechanical, thermal, and magnetic stresses during operation. To ensure their reliability and continuous operation, it is crucial to have real-time information on these constraints, often at a local scale. Wireless and battery-free sensor technologies, combined with effective data analysis and signal processing techniques, are essential to meet this need. Surface acoustic waves (SAW) allow the design of wireless and completely passive sensors capable of measuring various physical quantities such as temperature, mechanical stress, and magnetic fields, thanks to advanced design engineering. The work carried out in this thesis has enabled the development of multi-quantity SAW sensors for measuring deformations, temperature, and magnetic fields. These sensors were first calibrated on laboratory test benches and then used to characterize the mechanical properties, such as magnetostriction, and magnetic properties, such as magnetic losses, of ferromagnetic sheets used in the design of high-power electrical machines. Characterizing the properties of ferromagnetic sheets is crucial for several reasons: designing efficient electromagnetic systems, minimizing vibrations and unwanted noise, controlling energy dissipation, preventing material fatigue, optimizing component design for energy efficiency, and developing heat-resistant components for reliability and durability. The thesis project involves JEUMONT Electric (a high-tech company specializing in energy conversion solutions), the AIMAN-FILMS group from IEMN, and the Numerical Tools and Methods team from L2EP. Each partner brings specific expertise to address the multi-physical instrumentation of high-power electrical machines

Résumé :

Dans ce travail de thèse, nous avons effectué des mesures de caractérisations magnétiques (cycles d’hystérésis, pertes, H_c…) à très haute température jusqu’à 600 °C, à l’aide d’un dispositif de caractérisation adapté à ces conditions extrêmes qui est un cadre Epstein que nous avons élaboré et réalisé. Sa validation a pu être vérifiée avec un cadre normalisé à température ambiante. Les mesures sont faites sur les deux types de tôles ferromagnétiques les plus utilisées : FeSi GO et NO. Les résultats montrent une réduction avec la température des pertes fer et des différents paramètres qui définissent le cycle d’hystérésis et dévoilent une similarité qui existe entre l’évolution du champ coercitif et les pertes par cycle. Par la suite, nous avons décrit les pertes et le champ coercitif en fonction de la température et la fréquence par des équations empiriques linéaires dans le cas de matériaux saturés et par une extension de l’équation de Bertotti à haute température via une identification de ses paramètres dans le cas des matériaux non saturés. Dans un deuxième temps, nous avons caractérisé l’isolation d’un conducteur destiné à être utilisé à haute température constitué par un fil guipé mica d’origine inorganique, en mesurant la tension des décharges partielles et de claquage. À partir de ces résultats, nous avons montré que l’inhomogénéité de cette isolation le long du conducteur provoque des décharges destructives sans l’apparition de décharge partielle. Ce type de fils est constitué d’une âme en cuivre entourée par une fine couche de nickel, l’influence de cette dernière a été magnétiquement caractérisée au cours de notre travail. L’ensemble de ces études confirment l’importance de la prise en compte des effets de la température élevée et répond aux besoins croissants d’améliorer l’efficacité énergétique dans les différentes utilisations du génie électrique
In this thesis work, we carried out a magnetic characterization measurements (hysteresis cycles, losses, H_c...) at very high temperatures up to 600 °C, using a characterization device adapted to these extremes conditions which is an Epstein frame that we have developed and implemented. Its validation is verified with a standard frame at ambient temperature. The measurements are performed by two types of ferromagnetic sheets mostly used: FeSi GO and NO. The results show a decrease with temperature in iron losses and different parameters which define the hysteresis cycle, and expose a similarity between the variation of coercive field and the losses per cycle. Subsequently, we described the losses and the coercive field as a function of temperature and frequency. That is done by a linear empirical equations in case of saturated materials and by an extension at high temperature of the Bertotti equation via an identification of its parameters in case of unsaturated materials. In a second phase, by measuring the voltage of partial discharge and of the electrical breakdown we characterized the insulation of a conductor intended to be used at a high temperature covered by mica; this later has an inorganic origin. These results show that the inhomogeneity of this insulation along of the conductor causes destructive discharges without appearance of partial discharges. This kind of wire consists of copper surrounded by a thin nickel layer and this later has been characterized magnetically during our work

Résumé :

Abstract Crackling noise refers to an intermittent series of pulses of broadly distributed amplitude and duration that is observed in different contexts from the crumpling of a sheet of paper to the flow of fluids in porous media. Studying crackling noise is interesting because it reflects key microscopic processes inside the material, with each crackle in the noise corresponding to an internal avalanche event. A distinct statistical feature of crackling noise is the presence of power law distributed noise pulses and long-range correlations which are the hallmarks of critical phenomena. Hence, the physics of complex non-equilibrium disordered systems provides the natural theoretical framework to tackle crackling noise. The present book reviews the statistical properties of crackling noise, providing an introduction to the main theoretical concepts needed to interpret them. The book also contains a detailed discussion of several examples of crackling noise in materials, including fracture, plasticity, ferromagnetism, superconductivity, granular flow and fluid flow in porous media. A final chapter discusses the relevance of avalanche behavior for biological systems.

Résumé :

In this article, we demonstrate a mechanical-mechanism enhanced thermomagnetic tweezer. The tweezer which utilizes a thermal-magnetic-mechanical converting consists of two cross-jointed Al arms, two Gd sheets, two NdFeB hard magnets, two thermoelectric generators (TEGs), and a ball bearing set. When comparing conventional thermomagnetic grippers, our thermomagnetic tweezer can grip either ferromagnetic or non-ferromagnetic objects and avoid producing temperature-influence to the gripped objects. Experimental results show that we can control TEGs to generate a temperature difference to operate the tweezer to grip small ferromagnetic objects (such as NdFeB hard magnet) and other non-ferromagnetic objects (such as PMMA bulk). The maximum gripping force produced by the tweezer operated by applying the DC current of 1.3 A with the voltage of 0.85 V is 0.59 newton. The corresponding gripping and releasing duration is 7.9 seconds and 8.1 seconds, respectively. According to these results, our tweezer would produce more practical objects-gripping applications.

Résumé :

<div class="section abstract"><div class="htmlview paragraph">Electrical steel, also known as silicon steel, is a ferromagnetic material that is often used in electric vehicles (EVs) for stator and rotor applications. Since the design and manufacturing of rotors require the use of laminated thin electrical steel sheets, the fatigue characterization of these single sheets is of interest. In this study, a 0.27mm thick non-oriented electrical steel sheet was tested under cyclic loading in the load-controlled mode with the load ratio R = 0.1 at room temperature. The specimens were prepared using the Computer Numerical Control (CNC) machining method. The Smith-Watson-Topper mean stress correction was used to find the equivalent fully reversed stress-life (S-N) curve. The Basquin equation was used to describe the fatigue strength of the electrical steel and the fatigue parameters were extracted. Furthermore, a design curve with a reliability of 90% and a confidence level of 90% was generated using Owen’s Tolerance Limit method. The fracture mechanisms under cyclic loading were also studied using a scanning electron microscope. Crack initiation was determined to initiate from one edge and propagate to the other. Although the fracture mechanism was transgranular, the fracture surface displayed distinct regions of fatigue damage and cleavage fracture. The presence of aluminium nitrate precipitate particles contributing to crack initiation was confirmed using the energy dispersive x-ray spectroscopy technique.</div></div>

Résumé :

Abstract Ferromagnetic soft materials can generate flexible mobility and changeable configurations under an external magnetic field. They are used in a wide variety of applications, such as soft robots, compliant actuators, flexible electronics, and bionic medical devices. The magnetic field enables fast and biologically safe remote control of the ferromagnetic soft material. The shape changes of ferromagnetic soft elastomers are driven by the ferromagnetic particles embedded in the matrix of a soft elastomer. The external magnetic field induces a magnetic torque on the magnetized soft material, causing it to deform. To achieve the desired motion, the soft active structure can be designed by tailoring the layouts of the ferromagnetic soft elastomers. This paper aims to optimize multi-material ferromagnetic actuators. Multi-material ferromagnetic flexible actuators are optimized for the desired kinematic performance using the reconciled level set method. This type of magnetically driven actuator can carry out more complex shape transformations by introducing ferromagnetic soft materials with more than one magnetization direction. Whereas many soft active actuators exist in the form of thin shells, the newly proposed extended level set method (X-LSM) is employed to perform conformal topology optimization of ferromagnetic soft actuators on the manifolds. The objective function comprises two sub-objective functions, one for the kinematic requirement and the other for minimal compliance. Shape sensitivity analysis is derived using the material time derivative and the adjoint variable method. Three examples are provided to demonstrate the effectiveness of the proposed framework.
