This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jusqu'à présent les modèles multi-corps d'interaction véhicule-voie ferroviaire utilisent principalement des composants rigides. De tels modèles présentent l'avantage d'un nombre de degrés de liberté limité permettant de réaliser des calculs en temps réel à basses fréquences. En revanche, ils ne permettent pas de prédire avec suffisamment de précision les spectres des efforts de contact roue-rail en raison de l'hypothèse d'éléments rigides qui est assez forte. Aussi ces modèles gagneraient à être améliorés en prenant en considération la flexibilité des éléments. Ceci est possible grâce au couplage éléments finis - dynamique multi-corps. Les travaux réalisés dans le cadre de cette thèse ont pour objectif, l'amélioration des prédictions des efforts d'interaction véhicule-voie par intégration d'essieux et de rails flexibles dans les modèles multi-corps du véhicule et de la voie. Des modèles éléments finis des essieux et de la voie ont été développés et couplés au modèle global de la dynamique multi-corps via des méthodes de réduction de modèles afin de gagner en précisions tout en limitant le nombre de degrés de libertés. Différentes configurations des modèles multi-corps du véhicule et de la voie avec des essieux et des rails flexibles ont été explorées afin d'évaluer les effets de la flexibilité des éléments sur les prédictions des efforts de contact. Les premiers modèles sont réalisés avec des essieux flexibles roulant sur une voie théorique parfaite sans défauts avec des rails rigides en alignement puis en courbe. Ces modèles ont été ensuite modifiés afin d'intégrer la flexibilité des rails ainsi que des excitations générées par les défauts des roues et des rails (usure ondulatoire, méplat de roue et joint de rail).
Download or read book Railway Transportation Systems written by Christos N. Pyrgidis and published by CRC Press. This book was released on 2021-10-31 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Railway Transportation Systems covers the entire range of railway passenger systems, from conventional and high-speed intercity systems to suburban, regional, operating on steep gradients, and urban ones. It also examines in depth freight railway systems transporting conventional loads, heavy loads, and dangerous goods. For each system, the text provides a definition; an overview of its evolution and examples of good practice; the main design, construction, and operational characteristics; and the preconditions for its selection. Additionally, it offers a general overview of safety, interfaces with the environment, forces acting on the track, and techniques that govern the stability and guidance of railway vehicles. This new edition brings two new chapters. One concerns pre-feasibility studies of urban rail projects, and the other analyses the operation of railway systems under specific weather conditions and natural phenomena. New material examines dilemmas, trends and innovations in rail freight transportation; a new definition for high-speed rail; a number of case studies; and an update of cutting-edge technologies. It is ideal for graduate students, engineers, consultants, manufacturers, and transport company executives who need a reference and guide.

Download or read book Condition Monitoring of Machinery in Non Stationary Operations written by Tahar Fakhfakh and published by Springer Science & Business Media. This book was released on 2012-03-19 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: Condition monitoring of machines in non-stationary operations (CMMNO) can be seen as the major challenge for research in the field of machinery diagnostics. Condition monitoring of machines in non-stationary operations is the title of the presented book and the title of the Conference held in Hammamet - Tunisia March 26 – 28, 2012. It is the second conference under this title, first took place in Wroclaw - Poland , March 2011. The subject CMMNO comes directly from industry needs and observation of real objects. Most monitored and diagnosed objects used in industry works in non-stationary operations condition. The non-stationary operations come from fulfillment of machinery tasks, for which they are designed for. All machinery used in different kind of mines, transport systems, vehicles like: cars, buses etc, helicopters, ships and battleships and so on work in non-stationary operations. The papers included in the book are shaped by the organizing board of the conference and authors of the papers. The papers are divided into five sections, namely: Condition monitoring of machines in non-stationary operations Modeling of dynamics and fault in systems Signal processing and Pattern recognition Monitoring and diagnostic systems Noise and vibration of machines The presented book gives the back ground to the main objective of the CMMNO 2012 conference that is to bring together scientific community to discuss the major advances in the field of machinery condition monitoring in non-stationary conditions.

Available in PDF, EPUB and Kindle. Book excerpt: L'objet de cette thèse est l'étude du renversement des trains à grande vitesse soumis à des forts vents latéraux. Pour simuler le phénomène deux axes de recherche ont été dégagés. Le premier axe traite de la mécanique du contact roue-rail et de la mécanique des solides et des liaisons en grands déplacements. Cet axe a donné lieu à l'incorporation du modèle de contact roue-rail STRIPES dans un modèle dynamique de véhicule écrit pour l'occasion. Au terme de cette modélisation, la cinématique de soulèvement de l'essieu a été approfondie et un critère global comprenant le déchargement et le soulèvement de l'essieu a été proposé. Le deuxième axe de recherche traite de la modélisation de la turbulence vue pas un véhicule en mouvement. En se basant sur la modélisation de la turbulence de Von Karman et en appliquant les travaux de Cooper, une formulation de la turbulence vue du train a été proposée. Cette formulation se prête bien aux calculs de sensibilité des véhicules par une méthode de Monte-Carlo. Avec une méthode de tir adaptée et un nombre contrôlé de simulation, la courbe de sécuritée vis-à-vis du renversement construite, les apports de cette méthode par rapport aux pratiques existants sont analysés et l'origine des différences est discutée.

This book was released on 2019-11-26 with total page 3006 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first Pan-American Conference on Soil Mechanics and Geotechnical Engineering (PCSMGE) was held in Mexico in 1959. Every 4 years since then, PCSMGE has brought together the geotechnical engineering community from all over the world to discuss the problems, solutions and future challenges facing this engineering sector. Sixty years after the first conference, the 2019 edition returns to Mexico. This book, Geotechnical Engineering in the XXI Century: Lessons learned and future challenges, presents the proceedings of the XVI Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XVI PCSMGE), held in Cancun, Mexico, from 17 – 20 November 2019. Of the 393 full papers submitted, 335 were accepted for publication after peer review. They are included here organized into 19 technical sessions, and cover a wide range of themes related to geotechnical engineering in the 21st century. Topics covered include: laboratory and in-situ testing; analytical and physical modeling in geotechnics; numerical modeling in geotechnics; unsaturated soils; soft soils; foundations and retaining structures; excavations and tunnels; offshore geotechnics; transportation in geotechnics; natural hazards; embankments and tailings dams; soils dynamics and earthquake engineering; ground improvement; sustainability and geo-environment; preservation of historic sites; forensics engineering; rock mechanics; education; and energy geotechnics. Providing a state-of-the-art overview of research into innovative and challenging applications in the field, the book will be of interest to all those working in soil mechanics and geotechnical engineering.
