  2. 1. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact

    Author : Roger Enblom; Mats Berg; Simon Iwnicki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; wear; wear prediction; wear model; wheel profile; rail; Vehicle engineering; Farkostteknik;

    Abstract : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. READ MORE

  4. 2. Simulation and Measurement of Wheel on Rail Fatigue and Wear

    Author : Babette Dirks; Mats Berg; Roger Enblom; Mark Burstow; KTH; []
    Keywords : multibody simulations; prediction; wear; RCF; wheel; rail; cracks; measurements; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The life of railway wheels and rails has been decreasing in recent years. This is mainly caused by more traffic and running at higher vehicle speed. READ MORE

  5. 3. Network-based urban growth - How centrality and accessibility to places shape land use

    Author : Leonard Carl Staffan Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban growth; transport infrastructure; network; accessibility; Land-use change; agglomeration; complex; urban planning; spatial interaction; GIS;

    Abstract : The world is experiencing unprecedented and rapid urbanization. To be able to handle this transformation and guide the design of these cities in the way the inhabitants want to have them, it is necessary to understand the drivers and perform planning beforehand.   Cities are complex systems.

  6. 4. Simulation of rail traffic : applications with timetable construction and delay modelling

    Author : Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). READ MORE

  7. 5. Simulation of rail traffic : Methods for timetable construction,delay modeling and infrastructure evaluation

    Author : Hans Sipilä; Bo-Lennart Nelldal; Thomas Siefer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Kapacitet; Järnvägsgruppen - Kapacitet; Transportvetenskap; Transport Science;

    Abstract : This thesis covers applications and proposes methods for using simulation in a more effectiveway and also in a wider context than normally used. One of the proposed methods deals withdelay modeling that can be used in a calibration process. READ MORE
