1. Elastohydrodynamic lubrication under non-steady conditions
Sammanfattning : The six papers presented in this thesis consider the effects on elastohydrodynamic lubrication (ehl) of non-steady conditions. The vast majority of ehl investigations, both experiemental and theoretical, utilise steady state conditions, i.e. constant load, velocity, geometry and temperature. LÄS MER
2. Lubrication at impact loading
Sammanfattning : .... LÄS MER
3. On random satisfiability and optimization problems
Sammanfattning : In Paper I, we study the following optimization problem: in the complete bipartite graph where edges are given i.i.d. weights of pseudo-dimension q>0, find a perfect matching with minimal total weight. LÄS MER
4. Nonlinear dynamic analysis of vertical rotors with tilting pad journal bearings
Sammanfattning : .... LÄS MER
5. 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
