  1. 1. Brake Judder

    Författare :Helena Jakobsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Brake judder is a braking induced, forced vibration occurring in different types of vehicles. The frequency can be as high as 500 Hz, but usually remains below 100 Hz and often as low as 10-20 Hz. The driver experiences judder as vibrations in the steering wheel, brake pedal and floor.

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

    Författare :Mikael Eriksson; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems

    Författare :Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Wolfgang Kropp; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; disc brake; surface topography; wire brush noise; roughness noise; component mode synthesis; vehicle suspension;

    Sammanfattning : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. LÄS MER

  5. 4. 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

  7. 5. Simulation of Thermal Stresses in a Brake Disc

    Författare :Asim Rashid; Niclas Strömberg; Tore Vernersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis thermal stresses in a brake disc during a braking operation are simulated. The simulations are performed by using a sequential approach where the temperature history generated during a frictional heat analysis is used as an input for the stress analysis. LÄS MER
