  1. 1. Simulation of Wheel and Rail Profile Evolution : Wear Modelling and Validation

    Författare :Roger Enblom; KTH; []
    Nyckelord :contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. LÄS MER

  2. 2. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact

    Författare :Roger Enblom; Mats Berg; Simon Iwnicki; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; wear; wear prediction; wear model; wheel profile; rail; Vehicle engineering; Farkostteknik;

    Sammanfattning : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. LÄS MER

  3. 3. On wear of wood-cutting tools : Tool materials, wear mechanisms and modelling

    Författare :Johan Nordström; []
    Nyckelord :Tool material; Wood cutting; Wear; Modelling;

    Sammanfattning : Bandsaw blades are commonly used in the sawmill industry for timber cutting. The saw teeth are gradually worn during cutting and will finally cause unacceptable surface roughness and dimensional deviations on the sawn wood product. Maintenance by re-sharpening of the saw teeth is therefore necessary after a certain time of sawing. LÄS MER

  4. 4. Non-Exhaust PM10 and Road Dust

    Författare :Joacim Lundberg; Sigurdur Erlingsson; Mats Gustafsson; Sara Janhäll; Göran Blomqvist; Brynhild Snilsberg; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Road Dust; Abrasion Wear; Road Surface Macro Texture; Mean Profile Depth; Mean Texture Depth; Emissions; Abrasion Wear Model; NORTRIP; PM10; Air Quality; Particles; Vägdamm; Vägslitage; Dubbslitage; Textur; Emissioner; Slitagemodell; NORTRIP; PM10; Partiklar; Luftkvalitet; Byggvetenskap; Civil and Architectural Engineering; Dust; Inhalable particle; Pavement; Tyre; Wear; Abrasion; Health; 15 Road: Environment; 15 Road: Environment;

    Sammanfattning : Non-exhaust PM10 is an issue in the urban environment linked to health issues. Emissions of non-exhaust PM10 is relatable to pavement properties. Also of importance is resuspension of road dust stored from surfaces. This depends on the traffic and metrological conditions. LÄS MER

  5. 5. Wear in cone crusher chambers

    Författare :Mats Lindqvist; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cone crusher; modelling; wear; rock crusher; work hardening;

    Sammanfattning : Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock. A cone crusher consists of a fixed conic liner called concave and inside it a smaller moving liner called mantle. The mantle is suspended on an eccentrically rotating shaft. LÄS MER
