  2. 1. Friction and contact phenomena of disc brakes related to squeal

    Author : Mikael Eriksson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Tribology; contact mechanics; squeal; brake pad; disc brake; friction; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Brake squeal is a sound with a main frequency between 1 and 20 kHz, generated by an oscillation of the components of the brake system. The energy driving the oscillation is supplied by the friction between the disc and the pads. READ MORE

  4. 2. 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

  5. 3. High Efficiency Inductive Power Transfer Systems for Vehicle Charging

    Author : Daniel Pehrman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dual-active bridge; power flow control; bi-directional; electric vehicles; electromagnetic fields; inductive power transfer; high efficiency; high power; three-phase;

    Abstract : Awareness of climate change due to greenhouse gas emissions and air pollution has led to a transition from internal combustion engine vehicles to electric vehicles. Wireless charging by inductive power transfer is a promising solution for charging electric vehicles. READ MORE

  6. 4. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

    Author : Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; proteins; circularity; superabsorbents; sustainability; acylation; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. READ MORE

  7. 5. A methodology to simulate automotive disc brake tribology and emissions

    Author : Gabriele Riva; Jens Wahlström; Tore Vernersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Abstract : Airborne particle emissions from road vehicles are one of the main issues affecting urban air quality. Vehicle disc brakes are one of the most important sources of non-exhaust emissions, which have recently been considered to be as important as exhaust emissions. READ MORE
