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. 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
3. Influence of thermal loading on mechanical properties of railway wheel steels
Sammanfattning : Material integrity and properties of wheels are critical in railway traffic, as wheels fulfil the important function of transferring load and traction from the vehicle to the rail track. Steels with a pearlitic microstructure are commonly used for wheels due to their height strength, low cost and good wear properties. LÄS MER
4. Numerical models to simulate wear and friction-induced heating in rough surface contacts
Sammanfattning : The study of friction and wear is a crucial element in the effort to reduce carbon footprint in technology. It is evident that friction and wear are responsible for a significant amount of global energy losses, emphasizing the need for research on the topic. LÄS MER
5. Continuum models and numerical methods for tribological systems
Sammanfattning : This thesis concerns the formulation of continuum mechanical models and the development of numerical methods for frictional heating, wear and damage in tribological systems.The models are formulated in the spirit of generalized standard materials, i.e. LÄS MER
