  1. 1. A study of airborne wear particles from automotive disc brakes

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

    Sammanfattning : 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. LÄS MER

  3. 2. Towards a simulation methodology for prediction of airborne wear particles from disc brakes

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

    Sammanfattning : 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. LÄS MER

  4. 3. Tribological nature of squealing disc brakes

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

    Sammanfattning : 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.

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

    Författare :Mattia Alemani; Ulf Olofsson; Jens Wahlström; Anders Söderberg; Staffan Jacobson; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Mandeep Singh Walia; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
