Full textThe subject of this PhD thesis is the statistical inference on Mino process that we define as a one-memory self-exciting point process which intensiy has a special form. We begin with a general description of self-exciting point processes and we present methods used to estimate the intensity parameters of these processes. We consider the special case of a one-memory self-exciting point process, used in signal processing. We call the process: the Mino process. This process can be interpreted as a renewal process which interarrival times that follow a special distribution that we study in details. In order to estimate the parameters of a Mino process intensity, we utilize the maximum likelihood method. We solve the likelihood equations with a Newton-Raphson algorithm. We show the efficiency of the method on simulated data. The convergence of the Newton-Raphson algorithm and, the existence and uniqueness of the maximun likelihood estimators are proved. Lastly, we construct a test of hypothesis to assess whether a point process is self-exciting or not

Full textCurrently, free-form surfaces are used in various fields of activity, such as a manufacturing moulds or matrix used to make the models. The free form surfaces present a set of curved zones, i. E. Concave and convex zones, these surfaces require a high quality level and reduced shape defects. Their machining is long, not optimized and costly, to date: the machining of free form surfaces is done using the spherical tool with respecting roughness quality. The object of this study is to minimize the machining time of the free-form surfaces using toric end mill cutter and parallel planes milling strategy, with respecting roughness quality. The analytical expression of the machining time is unknown and by hypothesis, it is assumed to be proportional to the paths length crossed by the cutting tool. Those paths length depend on the feed direction and the maximal scallop height criteria must not be exceeded. To have an optimal feed direction at any point, the surface is divided into zones with low variation of the steepest slope direction. The optimization problem was formulated in order to minimize the global path length. Furthermore, a penalty reflecting the time loss due to the movement of the tool from one zone to another one is taken into account. The optimization problem is to minimize the path long trajectory crossed by the tool on the surface while respecting scallop height criteria. The optimization parameters are the number and the geometrical of the zones and the optimal feed direction in each zone. To resolve this problem, several optimization methods are used: combinatorial optimization and stochastic optimization. These methods are applied on a test surface and after simulations, the results obtained present a significant saving of paths length compared to the machining in one zone with spherical tool

Full textThe aim of this thesis is to develop an optimized regeneration process for waste generated from injection molding. The study focuses on the impact of mechanical recycling on the mechanical and physical properties of blends of polyamide 6 (PA6) and polyamide 66 (PA66), changing the proportions of recycled material from 10% to 100% in increments of 10%. Six recycling cycles were conducted, and the properties of the blends were analyzed based on the recycled material content. Up to the sixth cycle, slight variations were observed in mechanical properties, except for elongation. Physical properties exhibited a trend of decreasing flexural strength and Young's modulus, with an increase in elongation. Microscopic analysis revealed that for PA6, porosity increased as the number of recycling cycles increased. The study also addresses the influence of hygrothermal aging on the studied polyamides, examining resulting changes in their mechanical properties. Following these notable modifications, a numerical simulation was performed to assess the impact of changes in recycled material characteristics on injection molding process parameters. The results indicate that several parameters, especially mold filling time and injected part cooling time, are influenced by material property changes. Defects such as air bubbles and weld lines were observed, emphasizing the importance of considering them in the manufacturing process. This study provides a comprehensive understanding of the effects of recycling on polyamide properties, as well as the practical implications of these changes in the context of injection molding.Keywords: Regeneration, Polyamide 6, Polyamide 66, Injection molding, Simulation

Full textPowers transmissions are commonly used in many areas, including aeronautics. The studied system in this thesis is a helicopter gearbox. Its purpose is to transmit the power generated by the turbine engine to the main gearbox and to adapt the rotational speed of the input shaft. Aeronautical gears are light weight in order to maximize the power to weight ratio of the system. With thin rims, the mass of the system is reduced but its flexibility is increased. These types of gears, subjected to large number of revolutions and severe operating conditions, are more likely to be exposed to failures such as abrasive wear, scoring or micro-pitting. The first objective of this PhD thesis is the understanding and the simulation of the abrasive wear process for spur and helical gears. The material removal calculation is based on the well-known Archard equation, adapted to lubricated contacts. During the different phases of flight (take-off, landing, hover flight), the specific working conditions change. Consequently, the quasi-static gearing behaviour, the lubrication and therefore the quantity of wear need to be adapted. To this end, a new methodology is proposed to accumulate wear depths over several and different working conditions. This methodology makes it possible to analyze the kinetics and the intensity of the abrasive wear process and deduce the most severe phases of flight. The second goal echoes the first one. Following the identification of the problem of abrasive wear, a multi-objective optimization of the quasi-static behaviour of the thin rimmed gear is proposed. The goal of this optimization, based on the search of optimal tooth modifications, is to reduce potential sources of gear failures, in particular localized overpressures on tooth flanks or the Almen factor governing scuffing. Due to the complexity of the problem, a meta-heuristic multi-variable optimization algorithm (MO-TRIBES) is introduced. Multiple mono- and multi-objective gear optimization examples are provided in order to improve the quasi-static behaviour of the aeronautical gear : minimization of fluctuations of the transmission error under load, reduction of the maximal contact pressures, decrease of the scuffing risk factors. The ideal type of tooth modifications is discussed. Finally, by using the optimization module, the amount of wear is significantly reduced and a comfortable lifetime extension for the studied gear is provided

Full textThe medical devices make up a specific group beside classical products by their actions on the patients’ health. By this indication, the use of such devices potentially induces risk on the patients’ health especially in case of failure or misuse. These products may be used by a large target of users themselves or assisted. This diversity in terms of references and possible use, combined to the critical aspect of these products implies a significant taking into account of the user and usability during the product design. This is all the more important because as the medical devices form a very innovative industrial sector linked to the technological advances. These developments need to be adapted to the users who do not have always all the knowledge needed to their use. Nevertheless, while the framework (standards and regulations) emphasis on the need to take into account the user, this approach is little implemented by the companies which are, for a large part, SME’s with limited resources. At the same time, some weaknesses about the tools and methods in matter of use analysis are present. Moreover, this approach collides with barriers induced by design habits, multidisciplinary context and constraints related to the medical field. In the aim to give a realistic industrial answer to implement the user into the design process, a quantification tool of usability was developed. This tool draws on measurement methods and dedicated results presentation towards designers and General Public. From the experimentations, the proposed index appeared consistent against a gold standard index (SUS) and adds more details in the results (tasks, panel priority about usability components). These feedbacks showed a high understanding level of this tool and a significant interest by the designers but also the General Public. In addition, the experimentations highlighted the positive contribution of the proposed tool in the design team communication but also in the design choice by implementing usability approach including the upstream phases, especially in creativity
