  2. 21. Vehicle dynamic analysis of wheel loaders with suspended axles

    Author : Adam Rehnberg; Annika Stensson Trigell; Lars Drugge; Peter Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hjullastare; arbetsmaskin; fordonsdynamik; fordonsteknik; Vehicle engineering; Farkostteknik;

    Abstract : The wheel loader is a type of engineering vehicle used primarily to move crude material over shorter distances. As the vehicle is designed without wheel suspension, wheel loader drivers are exposed to high levels of whole body vibration which influences ride comfort negatively. READ MORE

  4. 22. Assessment of fatigue resistance and strength in existing concrete structures

    Author : Håkan Thun; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : During the last few decades, it has become more and more important to assess, maintain and strengthen structures like bridges, dams and buildings. This is mainly due to the fact that: (a) many structures are getting old and many have started to deteriorate, (b) there is sometimes a need to increase the load carrying capacity of an existing structure due to e.

  5. 23. Railway bridge response to passing trains : Measurements and FE model updating

    Author : Johan Wiberg; Raid Karoumi; Lennart Elfgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : Today’s railway bridges are analysed in more detail for moving loads due to the increase in speeds and axle loads. However, these numerical analyses are very time consuming as they often involve many simulations using different train configurations passing at different speeds and many considerations to take into account.

  6. 24. Dynamic Train-Turnout Interaction – Mathematical Modelling, Numerical Simulation and Field Testing

    Author : Elias Kassa; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact forces; Karhunen–Loève expansion; dynamic train–turnout interaction; field test; wheel–rail contact geometry; stochastic analysis; switches and crossings; SRA - Transport;

    Abstract : Two models for simulation of dynamic interaction between train and turnout are developed. The first one is derived using a commercial software for dynamics of multi-body systems. READ MORE

  7. 25. Fatigue assessment of riveted bridges

    Author : Tobias Larsson; Mohammad Al-Emrani; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The majority of the railways used today were built in the beginning of the 20th century. Most of the bridges constructed at that time are still in service. READ MORE
