6. On Contact Mechanisms and Mechanical Transmission Performance
Abstract : This thesis consists of four papers, which treat the modelling of a spur gear set and a disc brake, and the interaction between the machine elements. Features of the performance are studied in relation to the initial stated assumptions. READ MORE

7. Wheel-rail contact modelling in vehicle dynamics simulation
Abstract : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena.

8. Cam Roller Contact : Surfaces and Tribology
Abstract : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. In the valve train, mechanical components such as camshafts and rollers are defined by specifications including more and more constraints concerning their ability to face wear thus prolonging lifetime.

9. Beam-to-Beam Contact and Its Application to Micromechanical Simulation of Fiber Networks
Abstract : This doctoral thesis covers the topic of modeling the three-dimensional fiber net- works with the finite element method. It contains the part addressing the numerical aspects of the modeling, namely, the contact formulation and application of the developed methods to the fundamental questions such as the effect of randomness in fiber properties and effect of fines and hygroexpansion.

10. Engineering model for curve squeal formulated in the time domain
Abstract : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. Squeal is common in curves of a radius lower than 200 meters. A single frequency dominates the radiated sound, which makes squeal a very tonal noise. READ MORE
