  1. 6. Simulation and Measurement of Wheel on Rail Fatigue and Wear

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

    Sammanfattning : 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. LÄS MER

  3. 7. Automation of Wheel-Loaders

    Författare :Siddharth Dadhich; Ulf Bodin; Fredrik Sandin; Ulf Andersson; Jerker Delsing; Juha Röning; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Automation and tele-remote operation of mobile earth moving machines is desired for safety and productivity reasons. With tele-operation and automation, operators can avoid harsh ergonomic conditions and hazardous environments with poor air quality, and the productivity can in principle be improved by saving the time required to commute to and from work areas.

  4. 8. Wheel-rail Interaction Analysis

    Författare :Tanel Telliskivi; KTH; []
    Nyckelord :Archard; rolling-sliding; Winkler; wear simulation;

    Sammanfattning : A general approach to numerically simulating wear in rollingand sliding contacts is presented in this thesis. A simulationscheme is developed that calculates the wear at a detailedlevel. LÄS MER

  5. 9. Sleepiness at the wheel

    Författare :Anna Anund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Prevention of road crashes is a major priority in most countries. The present thesis focuses on driver sleepiness and road crashes. LÄS MER

  7. 10. Prometheus at the wheel : Representations of road transport informatics

    Författare :Oskar Juhlin; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ethnography; engineering; representational practice; testing; technical demonstration; constructivism; road transport informatics; intelligent transportation systems; situated practice; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The dissertation deals with the challenge of developing information technology for road transport, a field often referred to as Road Transport Informatics. Oskar Juhlin studies in particular how engineers cope with the contingent and social aspects of the design process and of road use. LÄS MER
