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

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

    Abstract : 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. READ MORE

  4. 7. Integrated brake control : downhill driving strategies

    Author : Peter Lingman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transport efficiency; heavy duty trucks; road slope estimation; cruise controller; retardation economy; foundation brakes; mass estimation; brake heat fading; Auxilary brakes; downhill driving strategies; component wear;

    Abstract : In this thesis, downhill driving strategies that co–ordinate the different brake actuators in heavy duty vehicles have been developed. As a starting point, the vehicle features affected by the retardation system are investigated. READ MORE

  5. 8. Laboratory measurements of airborne emissions from car brakes for clean air

    Author : Guido Perricone; Ulf Olofsson; Fulvio Amato; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automotive brake; non-exhaust emissions; inertia brake dynamometer; airborne particles; PM10; PN; isokinetic sampling; Rebrake; volatiles; real driving cycle; car brake emission factors; running-in.; Bilbroms; icke-avgasemissioner; skivbromsdynamometer; luftburna partiklar; PM10; PN; isokinetisk provtagning; Rebrake; volatiler; verkliga körcykler; emissionsfaktorer; in-körning.; Machine Design; Maskinkonstruktion;

    Abstract : Brake systems are used to safely stop vehicles. The brake pads are pressed against the brake disc, transforming the kinetic energy of the vehicle into heat to be dissipated. READ MORE

  6. 9. 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

  7. 10. On improvement of cast iron brake discs for heavy vehicles

    Author : Gael le Gigan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brake disc; cast iron; hot spots; cracking; elevated temperatures; material modelling; finite element analysis; drag braking; material testing; rig experiment; fatigue assessment;

    Abstract : Disc brakes are commonly used in motorcycles, passenger cars, commercial vehicles, heavy-duty vehicles, passenger trains and landing gears of airplanes. Depending on the application, a wide variety of brake discs have been developed, with a multitude of designs, geometries and materials. READ MORE
