    Abstract : Truck transport offers a versatile way to ship goods in regional, long haulage and urban applications. However, the heavy truck sector accounts for 6 % of total greenhouse gas emissions in the European Union. Therefore, there is a need for a substantial reduction of these emissions to secure the sustainability of Earth for future generations. READ MORE

  6. 14. Evaluation of the Load Carrying Capacity of a Steel Truss Railway Bridge : Testing, Theory and Evaluation

    Author : Jens Häggström; Hans Pétursson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : A good deal of resources has been invested in building and maintaining existing infrastructure.Many structures are now becoming old and do not meet the requirements of an increasingtraffic load, or are reaching the end of their lifecycle. READ MORE

  7. 15. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels

    Author : David Wennberg; Sebastian Stichel; Per Wennhage; Ragnar Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich panels; rail vehicle; lightweight; optimisation; carbody; Vehicle engineering; Farkostteknik; Construction engineering; Konstruktionsteknik; Construction materials; Konstruktionsmaterial;

    Abstract : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. READ MORE
