  1. 1. Modelling the viscoplastic properties of carbon black filled rubber : A finite strain material model suitable for Finite Element Analysis

    Författare :Rickard Österlöf; Leif Kari; Alan Muhr; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcing fillers; rubber; finite strain; viscoplastic; förstärkande fyllmedel; gummi; finita töjningar; viskoplastisk; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : An increased environmental awareness, legal demands and the large part of total costs attributable to fuel cost are all incentives for the automotive industry to reduce fuel consumption. The optimal driveline to enable this reduction depends on the operational conditions and the available infrastructure. LÄS MER

    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Jukka Hyttinen; Lars Drugge; Jenny Jerrelind; James Busfield; KTH; []

    Sammanfattning : 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.

  5. 5. Eco-designed functionalization of polyester fabric

    Författare :Tove Agnhage; Guido Sonnemann; Isabelle Vroman; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-design; Life cycle assessment; Madder; Anthraquinone; Bioactive; Multifunctional; Polyester; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : There is an increased awareness of the textile dyeing and finishing sector’s high impact on the environment due to high water consumption, polluted wastewater, and inefficient use of energy. To reduce environmental impacts, researchers propose the use of dyes from natural sources. LÄS MER
