  2. 1. Truck tyre rolling resistance : Experimental testing and constitutive modelling of tyres

    Author : Jukka Hyttinen; Lars Drugge; Jenny Jerrelind; James Busfield; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Truck tyre; PRF; filler reinforced rubber; ambient temperature; rubber testing; parametrisation; Finite-element simulation; Lastbildäck; PRF; gummi; förstärkande fyllmedel; effekt av omgivningstemperatur; gummiprovning; parametrisering; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Global warming sets a high demand to reduce the CO2 emissions of vehicles. In the European Union heavy-duty road transports account for 6 % of the total greenhouse gases and one of the main factors affecting these emissions is related to the rolling resistance of tyres. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Truck tyre; PRF; filler-reinforced rubber; ambient temperature; rubber testing; constitutive modelling; parametrisation; rolling resistance; load cell; Fletcher-Gent effect; Payne effect; Lastbilsdäck; PRF; förstärkande fyllmedel; gummi; omgivningstemperatur; gummiprovning; konstitutiv modellering; parametrisering; rullmotstånd; lastcell; Fletcher-Gent effekt; Payne effekt; Teknisk mekanik; Engineering Mechanics;

    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

  5. 3. Vägval : lastbilsförare i fjärrtrafik - perspektiv på yrkeskultur och genus

    Author : Eddy Nehls; Billy Ehn; Magnus Berg; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; gender; masculinity; working culture; reflexivity; truck-driver; male myths; trucker; gender equality; freedom; participant observation; haulage business; class;

    Abstract : This thesis is an ethnological study of the truck-driver profession and an examination of the prerequisites for sexual equality and diversity in the haulage branch. The aim is to: from a cultural perspective, with a special focus on gender and masculinity, study truck-drivers as an occupational group. READ MORE

  6. 4. Look-ahead Control of Heavy Vehicles

    Author : Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Abstract : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. READ MORE

  7. 5. Investigation of Wheel Housing Flow on Heavy Trucks

    Author : David Söderblom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Increasing fuel prices and demands for reductions of emissions have led to a considerably increased interest in developing more efficient vehicles. Besides designing more efficient power units with lower fuel consumption and emission levels it is possible to increase the total efficiency of the vehicle by aerodynamic optimization. READ MORE
