  3. 2. Drum Brake Squeal

    Författare :Johan Hultén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction induced; squeak; vibration; drum brake; squeal; instability; self-excited; noise;

    Sammanfattning : Drum brake squeal is a common discomfort. The main goal of this thesis is to investigate the mechanisms that generate drum brake squeal and to create a base for the search for solutions. A series of steps towards the understanding of these mechanisms are taken. Firstly, a simple model for friction-induced vibration is presented. LÄS MER

    Sammanfattning : 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. LÄS MER

  5. 4. On improvement of cast iron brake discs for heavy vehicles

    Författare :Gael le Gigan; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Simulation and transient control of diesel engine compression brake

    Författare :Peter Templin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The recent development of sophisticated integrated powertrain control systems forheavy duty trucks, including handling of driveline oscillations and automated gear shiftingsystems, requires detailed simulation models during the development process. Thesemodels need to balance the demands for accuracy, ease of parameterization and simulationefficiency. LÄS MER
