1. Railway tread braking temperatures - Numerical simulation and experimental studies
Sammanfattning : Tread (block) braking is still one of the most common braking systems on railway vehicles. The action is carried out by pressing brake blocks against the tread of a wheel, which is also in rolling contact with the rail. LÄS MER
2. Tread Braking of Railway Wheels - Noise-related Tread Roughness and Dimensioning Wheel Temperatures
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
3. Towards enhanced mechanical braking systems for trains. Thermomechanical capacity of wheel treads at 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
4. Thermal Capacity of Railway Wheels - Temperatures, residual stresses and fatigue damage with special focus on metro applications
Sammanfattning : Tread (block) braking is still one of the most common braking systems on railway vehicles.The action is carried out by pressing brake blocks against the tread of a wheel, which is also inrolling contact with the rail. LÄS MER
5. Thermal impact on rolling contact fatigue of railway wheels
Sammanfattning : Rolling contact fatigue (RCF) is a very common and costly damage mechanism for rails and wheels. This thesis investigates the influence of combined thermal and mechanical loading on RCF of railway wheels on the basis of numerical predictions. LÄS MER
