  1. 1. Thermomechanics of block brakes

    Författare :Daniel Thuresson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction; pin model; contact mechanics; brake; thermo camera; thermomechanical; wear; freight train.; finite element; temperature measurement;

    Sammanfattning : Friction in sliding contacts plays an important role in tribology. Applications can be found in many engineering fields  such as braking of vehicles  in which friction brakes are by far the most common. Thus, an understanding of the mechanisms involved in friction brakes has become more important as the demands on brakes increase. LÄS MER

  3. 2. Characterisation of airborne particles from rail traffic

    Författare :Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Mats Gustafsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne; railway; brake; block; Other engineering mechanics; Övrig teknisk mekanik; SRA - Transport; SRA - Transport; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Sammanfattning : Since the investigation of wear particles in rail transport started in late-1910s, the high mass concentration of these particles has raised worries among researchers concerned with air quality. However, effective action has yet to be taken because of lack of relevant knowledge. LÄS MER

  4. 3. Towards elimination of airborne particles from rail traffic

    Författare :Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Yannick Desplanques; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Airborne; brake block; brake pad; railway; subway; TEI; wheel–rail; wear; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Sammanfattning : Since the investigation of wear particles from rail transport started in the late 1910s, the high mass concentrations of these particles have prompted concern among researchers interested in air quality. However, effective action has yet to be taken because relevant knowledge is still missing. LÄS MER

  5. 4. Prediction of engine component loads using previous measurements

    Författare :Pär Mikaelsson Elmén; Mårten Olsson; Jan-Olov Aidanpää; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine; engine block vibration; engine block twist; engine block bending; vibration measurement; vibration estimation; rigid body vibrations; assumed modes; bending modes; torsion modes; system modification; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Internal combustion engines are used in many applications. The same engine type may have different components mounted to it depending upon its use. These engine mounted components need to be designed against fatigue in order to withstand the engine vibrations. Measured engine vibrations are commonly used as input data for fatigue estimation.
