  2. 1. 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

  4. 2. Thermomechanics of block brakes

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

    Abstract : 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. READ MORE

  6. 4. 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. 5. A study of airborne wear particles from automotive disc brakes

    Author : Jens Wahlström; Ulf Olofsson; Werner Österle; KTH; []
    Keywords : Disc brakes; Airborne wear particles; Nanoparticles; Cellular automaton; Mechanical engineering; Maskinteknik;

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