  2. 16. Characterisation of airborne particles from rail traffic

    Author : Saeed Abbasi; Ulf Sellgren; Ulf Olofsson; Mats Gustafsson; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 17. Towards a simulation methodology for prediction of airborne wear particles from disc brakes

    Author : Jens Wahlström; Ulf Olofsson; Jens Wahlström; KTH; []
    Keywords : Disc brakes; Airborne wear particles; Particle coefficient; Friction; Mechanical engineering; Maskinteknik;

    Abstract : During braking, both the rotor and the pads in disc brakes are worn. Since disc brakes are not sealed, some of the wear particles generated can become airborne. READ MORE

  5. 18. Tribological nature of squealing disc brakes

    Author : Filip Bergman; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : In the stiff competition between car manufacturers, silent and vibration free brakes hasbecome increasingly important. The aim of the present work is to increase the knowledge of the fundamental friction mechanisms operating in brake systems and to study the parameters influencing disc brake squeal generation.

  6. 19. Mechanical braking systems for trains: A study of temperatures, fatigue and wear by experiments and simulations

    Author : Mandeep Singh Walia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tread brakes; experiments; temperatures; disc brakes; wear; Railway braking; simulations; fatigue;

    Abstract : Increased demand for shorter travel times, higher axle loads, increased volumes and increased punctuality of railway traffic calls for a better design and management of the railway subsystems. The present thesis deals with aspects of mechanical friction brakes, in the form of tread brakes and disc brakes. READ MORE

  7. 20. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface

    Author : Mattia Alemani; Ulf Olofsson; Jens Wahlström; Anders Söderberg; Staffan Jacobson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car brakes emissions; transition temperature; working conditions; environmental design; pin-on-disc; Bilbromsutsläpp; övergångstemperatur; arbetsförhållanden; miljödesign; pinne-på-skiva; Machine Design; Maskinkonstruktion;

    Abstract : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. READ MORE
