Abstract
This dissertation investigates how external vibrations can be used to influence and control friction. While friction is essential in many systems, it also leads to energy loss, wear, and inefficiencies. Traditional lubrication has limitations, making vibration-based methods a promising alternative. The study explores how factors such as excitation frequency, phase, load application, and system dynamics affect friction behaviour, as well as the interaction between friction and vibrations, including potential instabilities. By using more realistic system models, the research highlights the importance of system flexibility and dynamic properties, contributing to a deeper understanding of friction in complex systems and offering insights for practical applications.
