Full textThis work has for objective the study of the default involving to low level thin gold layer connectors for printed circuit boards failure. Several parameters can be at origin of a «false contact» in this kind of connector: loss of force due to the relaxation of springs, corrosion and pollution. If solutions were brought to protect against the corrosion (gold deposit in contact areas), loss of the mechanical properties of the contacts is inevitable because of the long lasting of life planned by these connectors (40 years initially). Their remaining life expectancy represents a major stake and requires to be known. To answer it, evolution of various parameters that characterize these connectors, such as insertion force, contact force, springs deflection, and contact resistance, is studied for a high number of operations of insertion/withdrawal phases thanks to insertion and friction contacts benches realized. EDX Analysis of the contact areas is made to estimate importance of contact surface damages. . Once these parameters known, an innovative prototype sensor for force measurement was developed for connector, based on piezoresistive effect, allows direct measurement of contact force. A major observation during those measures of force with this sensor is variation of this one according to contacts. The geometric tolerance of connector housing is assumed to be the major explanation of these variations. A correlation is made between measurements obtained by force sensor and measurements of distances between springs (difference of gap) obtained thanks to a visual inspection system for connectors with the aim to find an effect of causality between those two parameters
Strubel, Nicolas. "Brake squeal : identification and influence of frictional contact localizations." Electronic Thesis or Diss., Université de Lille (2022-....), 2023. http://www.theses.fr/2023ULILN059.
Full textAs intense acoustic radiations implying consequent environmental nuisances and customer complaints, squeal noises in brake systems are friction-induced vibration issues indubitably depending on multiphysics and multiscales problematics. Among these latter, system structure, braking operational parameters, frictional contact interfaces, coupled to temperature dependency, as well as contact non-linearities or tribological aspects, are elements considerably affecting squeal, making from this unpleasant noise a complex problem to apprehend. In this work, the full scale system is considered, and several principal tendencies are identified regarding the influence of contact localizations on acoustic emissions.NVH tests are conducted, this analysis involves several scales of interest aiming at changing contact characteristics: pads are modified either at the macroscopic scale -with the will of implicitly varying load bearing areas-, or at the mesoscopic one -tending to impact evolution of the tribological circuit-. The inherent purpose is to identify pads parameters influencing squeal, by affecting tribolayer as well as engaging noise signature differences between conducted experiments.Heavily instrumented tests are realized on a full scale brake system, focusing on different pad shapes: the development of an enriched instrumentation through in-operando thermal surface tracking allows to access to supplementary solicitation informations, permitting to follow the assumed load bearing area. The employment of clustering methods is considered to manage the analysis of thermal datas.Experimental / numerical correlated stability simulations are conducted. Subsequent analyses are realized, by investigating pads chamfer characteristic impact on squeal, influence of coefficient of friction, or implementation of global pads wear shapes. Furthermore, thermomechanical simulations are of interest, and the introduction of previously clustered-defined contact areas into models is realized.Although the full brake system consideration can involve severe experimental dispersions, initial correlations between modified pads at different scales -via pad shapes for the macroscopic one, and thermal treatments of friction material focusing on the mesoscopic level- and noise characteristics are observed. Enriched instrumented tests lead to the conclusion that contact localizations can evolve during NVH tests, depending on solicitation variables. A particular link between braking operational parameters (pressure, temperature), contact localizations, and squeal features is established through clustering. Finally, observed simulated tendencies tend to follow experimental ones, and model enrichment via a more accurate contact description could present improvements regarding squeal prediction capability of such simulation

Full textLa mesure MEMS a permis d'obtenir les champs de contrainte sous charge normale et en glissement stationnaire, en très bon accord avec des modèles mécaniques simples. Pour des substrats de rugosité périodique le lien entre spectre des contraintes et topographie de surface a pu être interprété en termes de filtrage spectral, pertinent pour comprendre la perception tactile.
La mesure optique a permis, en analysant la répartition spatiale de l'intensité, d'obtenir le champ de pression de surface. Sa dépendance avec les propriétés de la couche rugueuse a été confrontée au modèle de Greenwood-Tripp. Par suivi des aspérités, le champ de déplacement a été mesuré avec une résolution sub-micronique et a mis en évidence la coexistence de zones glissantes et adhérentes prédite par Cattaneo et Mindlin.

Full textThe aim of this thesis is the study of some boundary value contact problem, with or without friction, between a body and a foundation. We consider the case of small deformations and we study quasistatic process for elastic, viscoelastic and viscoplastic materials. The results obtained concern the existence and uniqueness of weak solutions as well as the behaviour of the viscoelastic solutions as the viscosity converges to zero. The thesis is structured in four parts. In the first part we present the different mechanical models and we recall some tools of functional analysis. The second part is devoted to the study of viscoelastic frictionless contact problems with normal compliance and Signorini condition. In the third part, we are interested in the study of antiplane problems with Tresca's friction, for linearly elastic and viscoelastic materials. Finally, the fourth part is devoted to the study of viscoplastic contact problems with normal damped response and friction

Full textIn a classical finite element model, physical and material properties as well as the boundary conditions are generally considered as being deterministic and constant in a statistical sense. With this observation in mind, the validity of the solution obtained from such a model could be questionable. However, accepting that the laws of physics evolve randomly raises many questions. To address them, this research project will use the stochastic finite element method to study some academic and industrial applications to analyze the effect of random variation of the parameters of these laws on the solution. The discretization is a key step of this method which contributes to the construction of the matrix system. After applying conditioning technique, it’s possible to build the finite element response after resolution. When the probability is associated with some parameters which constitute this system, then only the finite element discretization is no longer sufficient to produce the new matrix system which has random or stochastic process not already included in the equations. The use of the stochastic finite element method provides the way to include adequate probabilistic technique to makes an efficient reliability and a probabilistic study of the mechanical contact problem

Full textAn object is said to be slender if at least one of its dimensions is small compared to the others. This characteristic makes it possible to impose important deformations on it while remaining in the elastic domain. If we assemble several of these objects, predicting the mechanical response of the assembly requires taking into account contact effects including friction and adhesion. In this thesis, we study two kind of assemblies. The first one is ensemble of plates and the second one of beams. We study in the first part two booklets whose pages are inserted two by two, a type of assembly that has become popular for the impressive results it produces when made with phonebooks. We have characterized the origin of the force that keeps the two booklets interleaved. In the second part we study the compression of a bundle of fibers connected by their ends. We also discuss the link between these experiments and the physics of painting
