Full textThe present work concerns the development of a software tool for the design of electromagnetic actuators. The tool is based on a hybrid methodology associating analytical and numerical approaches. The association is carried out by coupling a commercial software tool (Pro@Desing) for analytical calculation, and a software under developement in the Laboratoire de Génie Electrique de Paris (LGEP) for numerical calculation using the Finite Element Method (FEM). The analytical approach uses a model which deals with global quantities and ensure an overall view of the behaviour of the coupled electromagnetic-thermal phenomena. It permits also to analyse the influence of the different geometrical parameters on the actuator outputs using an optimisation procedure. The temperature and dimensions of the different motor parts are calculated simultaneously. The strong coupled model is based on the materials constituve laws which make explicit the interdependence between electromagnetic and thermal phenomena. The numerical approach deals with local variables and informs about space-time variations of the various quantities. In the considered methodology, the numerical analysis is employed after the analytical one first to validate the analytical solution then to complete the design procedure. At last, the mechanical response of the actuator structure to the magnetic forces excitation is determined by a harmonic analysis. A weak coupled magneto-mechanical model based on the FEM is developed. It allows to benefit from the preciseness of finite element calculation without penalizing the calculation time

Full textIn order to avoid surgery for battery replacement or recharge, we propose to use an innovative technique to wirelessly recharge the battery using magnetoelectric materials. The magnetoelectric effect is issued of two combined phenomena: piezoelectricity and magnetostriction. The idea is to achieve a wireless power transmission based on the near magnetic field techniques: the source energy is emitted via a magnetic field and the receptor which will transduce the energy is a magnetoelectric material. The magnetostrictive part of the magnetoelectric transducer is subjected to a stress due to the magnetic field. The stress is transmitted to the piezoelectric part which will produce an electric field. The electric voltage collected from the electrodes of the piezoelectric material will be used to power or recharge electronic devices. This thesis contributes to the development of this technique by proposing improving ways for energy transmission to powering sensors with the smallest transducer possible. An 2D finite element model his presented with power measurements and the characterizing bench associated

Full textCanned motor pumps are one of the safest ways to pump dangerous (radioactive, toxic), expensive and volatile fluids in nuclear and chemical fields. The canned motor pump is a compact unit integrating a hydraulic part and an induction motor with a common shaft. The special feature of the motor is that two non-magnetic cylindrical tube called “the can” are inserted into the air gap to seal the rotor from the stator windings. The pumped fluid passes through the air gap to cool the motor and lubricates the bearings. The new European standards on the motor efficiency (IEC standards), the increase in the service life of nuclear power plants in France, as well as the increased safety of the nuclear power plant installations after the Fukushima catastrophe are the reasons why canned motor pumps have to be designed with better efficiency and service life while fulfilling safety functions. The purpose of this PhD thesis is to develop a multiphysical model combining the electrical and thermal parts of canned motor to determine the efficiency and service life of canned motor. The reliability of the established multi-physical model has been validated by a comparison with the experimental test results carried out on different instrumented prototype motors. An analysis of the influence of parameters that determine the electrical and thermal performances of the canned motor was carried out and indications on the redesign of canned motor pumps were formulated to have motors with better efficiency and longer service life

Full textThe electronic equipment design industry is undergoing rapid transformations, characterized by increasing demands for performance, stringent sustainability standards, and growing budgetary and environmental constraints. Numerical simulation has become essential to address these challenges, but it is often limited by a fragmented approach that does not integrate different physical domains. Thales SIX, operating in sectorssuch as Defense, Security, and Aeronautics, is particularly affected by these issues.This thesis proposes the development of a methodology for constructing multiphysical simulations, enabling the creation of Digital Twins. These Digital Twins, virtual representations of real systems, integrate various physical domains such as thermal, mechanical, and electromagnetic, aiming to optimize the design of complex products by considering the interactions between these domains.The research methodology is based on three main stages :1. Model-Based System Engineering (MBSE) : This phase involves creating a robust systemic architecture,led by a Systems Modeling Architect, to coordinate the various involved disciplines and ensure the coherence of the systemic approach.2. Model Reduction : An in-depth investigation of model reduction techniques is conducted to decrease the size of 3D simulations, essential for enabling fast and real-time evaluations.3. Multiphysical Coupling : This stage aims to coherently integrate the different physical aspects to create realistic simulations that accurately reflect the behavior of electronic equipment under various conditions.The results of this thesis demonstrate that the developed methodology can significantly improve the design processes of complex systems by validating physical architecture choices, enhancing system performance, and reducing development costs and time. It also offers promising perspectives for future research, such as the development of specific tools to include the new simulation architecture view in MBSE tools, simplifying the methodology, and evaluating it on more complex case studies.In conclusion, this thesis makes a significant contribution to research and engineering practices by proposing an innovative methodology for creating advanced multiphysical simulations, essential for addressing the technological and operational challenges in the electronic equipment design industry

Full textThe work presented concern the analytical modeling and optimization of high speed permanent magnet synchronous machines for Hybrid Electric traction motor.However, such an application accumulates difficulties of electromagnetic, thermal and mechanical order. The first part is interested in establishing a state of the art of the high-speed applications’ particularities. Then, a simplified multiphysic and analytic modeling was implemented to conduct a first comparison between four kinds of PM rotors. This was based on a multi-objective optimization in order to optimize the delivery speed while improving the cycle efficiency. In order to achieve the desired performance, precise multiphysics interactions’ modeling was performed. Bolts opposing this improvement are well known and are mainly related to the compactness of the desired structures.The core of the proposed interactive modeling is the electromagnetic modeling which, using a reluctance network, allows to choose between two kinds of control: current control or voltage control. The high speed constraint requires serious interest to iron and mechanical losses. In this work, we are interested in developing a mechanical model which estimates the maximum speed which can be integrated easily into an optimization procedure. The model is then coupled with a particle swarm algorithm in order to involve the optimal sizing approach.These works join within the framework of the project ANR AAP TTD "e-MECA" (électromécanique Embarquée à Compacité Améliorée) where the partners are: Valeo (project leader), SKF, IFPEn, TEMPO, Dynfluid and SATIE

Full textSince Phenix shutting down in 2010, CEA does not have Sodium Fast Reactor (SFR) in operating condition. According to global energetic challenge and fast reactor abilities, CEA launched a program of industrial demonstrator called ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration), a reactor with electric power capacity equal to 600MW. Objective of the prototype is, in first to be a response to environmental constraints, in second demonstrates the industrial viability of:• SFR reactor. The goal is to have a safety level at least equal to 3rd generation reactors. ASTRID design integrates Fukushima feedback;• Waste reprocessing (with minor actinide transmutation) and it linked industry.Installation safety is the priority. In all cases, no radionuclide should be released into environment. To achieve this objective, it is imperative to predict the impact of uncertainty sources on reactor behaviour. In this context, this thesis aims to develop new optimization methods for SFR cores. The goal is to improve the robustness and reliability of reactors in response to existing uncertainties. We will use ASTRID core as reference to estimate interest of new methods and tools developed.The impact of multi-Physics uncertainties in the calculation of the core performance and the use of optimization methods introduce new problems:• How to optimize “complex” cores (i.e. associated with design spaces of high dimensions with more than 20 variable parameters), taking into account the uncertainties?• What is uncertainties behaviour for optimization core compare to reference core?• Taking into account uncertainties, optimization core are they still competitive? Optimizations improvements are higher than uncertainty margins?The thesis helps to develop and implement methods necessary to take into account uncertainties in the new generation of simulation tools. Statistical methods to ensure consistency of complex multi-Physics simulation results are also detailed.By providing first images of innovative SFR core, this thesis presents methods and tools to reduce the uncertainties on some performance while optimizing them. These gains are achieved through the use of multi-Objective optimization algorithms. These methods provide all possible compromise between the different optimization criteria, such as the balance between economic performance and safety

Full textThis thesis focuses on the design of high-speed, low-power permanent magnet motors specifically intended for driving a counter-rotating compressor. The primary objective is to ensure direct and compact integration of the motor, both in terms of length and volume, within the compressor wheels. To meet these requirements, several motor topologies—axial flux, radial 268 flux, and an innovative conical airgap structure—were modeled and evaluated. These evaluations included an in-depth analysis of electromagnetic and thermal performance, aimed at maximizing motor efficiency at high speeds. Particular attention was given to the study of electromagnetic losses, which become significant at these high speeds, for each of the considered topologies. In parallel, detailed mechanical analyses were conducted on disc-shaped rotors, which are sparsely documented in the literature, as well as on cylindrical rotors, to characterize their mechanical behavior at a rotational speed of 90,000 rpm. Manufacturing constraints ultimately led to the selection of the radial flux topology, which is currently under prototyping

Full textNumerical simulations are widely used during the design phase of a product but also for the validation of an innovative system. For example, during the conception of an electric vehicle’s powertrain, numerical simulations can be used to select the appropriate electric engine technology or for the development of control strategies taking into account decision criteria such as vehicle’s autonomy, but also its cost and performance.System’s complexity is always increasing, so they require more and more precise simulations in order to better understand the phenomena involved - for example to study iron losses in an electric engine. 3D simulations provide very accurate results to study a body but are still not appropriate today for the study of large scale systems (ie. with many degrees of freedom, many optimization parameters and several areas of Physics). Indeed, 3D simulations computing time cost is directly linked with the number of degrees of freedom. That’s why, in recent years, model order reduction techniques stir developments because they guarantee a good compromise between the computation time and accuracy of results produced by these models.In this study, we are interested in techniques that can be used in an industrial context around two axes: - the study of thermal phenomena (in the power electronics modules) - the study of electromagnetic phenomena (in electric engines)
