  3. 2. Numerical and Experimental Investigations on Aerodynamic and Thermal Aspects of Rotating Wheels

    Författare :Alexey Vdovin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation resistance; wind tunnel; brake cooling; ride height; aerodynamic moment; CFD; rim design; vehicle aerodynamics;

    Sammanfattning : With todays and future environmental legislations for CO2 and other emission gases, all vehicle manufacturers are forced to further develop tools and methods to make their vehicles more energy efficient and environmentally friendly. One option to achieve this is to reduce the aerodynamic resistance since it has a significant influence on the vehicle fuel consumption, especially for velocities higher than 50 km/h. LÄS MER

  5. 4. Thermomechanical behaviour of tread braked wheels

    Författare :Eric Landström Voortman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical analysis; high temperature testing; thermal analysis; full-scale brake rig testing; tread braking; Railway wheels; finite element analysis;

    Sammanfattning : Tread brakes, also known as block brakes, are a type of friction brakes commonly used in the railway industry. They are a low-cost and low-maintenance solution compared to more complicated systems such as disc brakes or electrodynamic brakes. LÄS MER

  7. 5. Tread Braking of Railway Wheels - Noise-related Tread Roughness and Dimensioning Wheel Temperatures

    Författare :Tore V Vernersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail chill; block material; temperature; heat partitioning; railway; corrugation; thermoelastic analysis; tread braking; noise;

    Sammanfattning : Block braking is a commonly used braking system for freight wagons and other types of railway vehicles. One or several brake blocks are pressed against the tread (running surface) of the wheel, which is also in rolling contact with the rail. LÄS MER
