Hairoud, Siham. "Modélisation dynamique des canaux MIMO pour les transports ferroviaires". Thesis, Poitiers, 2012. http://www.theses.fr/2012POIT2256/document.
The exploitation, control and signalling systems for metro and especially modern driverless metros, are based on two families of radio communication systems Wireless : vital transmissions for signalling and train control low-flow and nonvital transmissions with very high bandwidth for video-tracking systems, telediagnosis, customer information, etc.. During the implementation ofsuch transmission systems, the industrial must therefore ensure the metro operator performance on throughput and transmission quality in terms of packet loss information. Therefore, understanding the behavior of the propagation channel is a key to predict and improve performance of transmission systems.The aim of this thesis is twin and concerns :• On the one hand, the computation time reduction of a 3D ray tracing simulator that accurately predicts the behavior of the propagation channel, but it is expensive in times of calculation for dynamic simulations. We propose here a new method based on three visibility criteria to simplify the geometry description of the environment without degrading the characteristic parameters prediction of the propagation channel ;• On the other hand, the construction of a new model for MIMO propagation channel dynamics in straight tunnel of rectangular section which will optimize transmission systems multi-antennary (MIMO) applications for wireless transmission in metros tunnel. This model draws broadly from the channel model used in the standard WINNER and is fed by the results extracted from the 3D ray tracing channel simulator. The results obtained in this thesis are encouraging and offer many opportunities

The third generation TGV sets (French Railways high spee trainsets) will be double-decker trainsets (also known as TGV - 2N) travelling at 350 km/h in commercial service. This study relates to the insertion of composite materials in order to reduce the the weight of the TGV 2N bogie structure. A research on a new concept has been conducted and led to the specification of an experimental model of bogie in box shaped elements obtained by a statification method. The behaviour of the materials has been charaterized both in staic and in fatigue where damage laws and wohler curves have been estabilished. The static and dynamic behaviour of the experimental model has been modelled. The modelling was then used to validate the concept in relation to the static resistance criteria and to modal analysis prosperties and especially to validate finite elements calcultaion models thanks to SAMCEF software. Lastly, the validity of the concept in relation to the fatigue has been experimentally achieved and it was possible to draw degradation and failure laws. This study will be able to be used as the basis of more precise research on a new industrial concept of a bogie made of composite materials which will take into account both functional and economic criteria

This thesis concerns the hybrid traffic flow modelling and simulation. This approach uses jointly the two classical traffic flow models ; macroscopic and microscopic. It is a matter of adapting the representation to the studied phenomenon. Indeed, the macroscopic model is well adapted to the motorway network representation whereas the microscopic one makes it possible to describe an urban network more finely. Thus, we can obtain detailed information of the traffic state on a crossroads (for example) using the microscopic model and to implement traffic control laws synthesized from a macroscopic one. The final objective is to design and implement a decision-making tool allowing us to test and validate various traffic control strategies. For that, we initially developed a microscopic model founded on the paradigm agent. Then, we have proposed a coupling procedure, which makes it possible to ensure the conservation and the continuity of flow through the transition zone that connect the two worlds ; microscopic and macroscopic. The simulation results of the developed hybrid model show that it is possible to cohabit two models (microscopic and macroscopic) within the same system. To illustrate the relevance of the hybrid model, a traffic flow control application has been proposed. The results show that the vehicles travel total time was reduced. The proposed model represents a first version of a traffic flow hybrid simulator, which will remain to be developed within the furthers works

This research proposes an interactive operational transport and land use model like a tool of transport planning aid. The construction of this model falls under a will to exceed the traditional methodology of the strongly criticized models of transport owing to the fact that they badly take into account the character derived of the travel demand, in particular, the locations of the residents and of the activities, generators of travel, are regarded as fixed. In the long run, the interactions between transport and land use must be explicitly integrated. The modification of the conditions of travel has impacts on the urban forms and the effect of these forms on the travel demand is not a doubt. The implementation of such a model requires an analysis of the travel demand, initially, and a conceptual and theoretical analysis of the mechanisms of interaction between transport and land use in the second time. That is the subject of the first part of this work. The second part of the thesis is devoted to the development of an interactive model of transport and urbanisation. This one articulates three submodels: a model of urban development which takes as a starting point the theory of the urban economic base, a model of urban structure which estimates the distribution of the locations of the residents and the induced activities. Lastly, a model of travel which expresses the market equilibrium of the urban transport obtained through the stages of generation, spatial distribution, modal split and assignment. The dynamics of long term of the model is obtained by the introduction of retroactive loops. The model brings certain lesson for the transport planning. The latter must fall under a total step and of long term, and must be considered in coherence with the urban planning

In an urban congested background where the number of personal vehicles keeps on growing, managing other vehicles becomes more and more useful and necessary. To evaluate different strategies, two types of traffic flow models can be used : microscopic models describe each individual vehicle and macroscopic models consider the flow in a global and homogenous manner. Stradabus proposes to adapt a macroscopic model in a way to take buses and their interaction with traffic into account as could behave a moving bottleneck. The model resolution introduces a new discretisation scheme around the bus. Measures have been experimented in the field that allowed calibration and validation of the model
Labergri, Fabien. "Modélisation du comportement dynamique du système pantographe-caténaire". Ecully, Ecole centrale de Lyon, 2000. http://www.theses.fr/2000ECDL0012.
This study, a collaboration between ECL-SNCF-FAIVELEY TRANSPORT, proposes a mechanical model of current collection. It led to simulation software written in C++, named PACAT3D. The work includes the development of pantograph and of catenary models and numerical methods to deal with and the pantograph / catenary coupling equations. The pantograph is modelled with the help of multibody methods. Absolute nodal coordinates are used in order to simplify the definition of the joints. The non-linear damper of the pantograph has been thoroughly studied. A large experimental work has been used as a guideline for the models development and allowed their validation. The catenary is modelled by finite-elements. The non-linearity arising from the droper's release are taken into account. A study on the three dimension behaviour of the catenary has been carried out. Techniques to handle systems of equations with constraints are describe : their transform to fit with explicit integration methods, static calculus, constraint relaxation and reestablishment. Many strategies are tested in order to find out the contact force between the mobil pantograph and the discretized catenary; particulary the use of wire elements obtained through modal synthesis. An analytical method enable the validation of the pantographjcatenary coupling. It applies to the stationary response study of a moving pantograph under an infinite periodical catenary. Based upon the Fourier series decomposition of the variables expressed in the moving frame, it leads to the resolution of an eigen value problem
