    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

  5. 4. Towards enhanced mechanical braking systems for trains. Thermomechanical capacity of wheel treads at stop braking

    Författare :Mandeep Singh Walia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; full-scale brake rig testing; tread braking; rolling contact fatigue; high temperature fatigue; Railway wheels; stop braking;

    Sammanfattning : Modern trains are equipped with different braking systems, between which the braking effort can be distributed. Among these, tread braking is still the most common system for friction braking. Tread brake systems are cheap and robust. LÄS MER

  7. 5. Modelling of cyclic and viscous behaviour of pearlitic steels. Application to tread braked railway wheels

    Författare :Ali Esmaeili; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway wheels; viscoplasticity; tread braking; rolling contact fatigue; full-scale brake rig testing; finite element analysis; plasticity;

    Sammanfattning : Railway wheel and rail materials are subjected to very high stresses and, in some cases, also elevated temperatures. The rolling contact loading results in a multiaxial stress state with a combination of compression and shear. LÄS MER
