Organizer

Per Johansen, Aalborg University

Lecturer

Per Johansen, Aalborg University

ECTS: 4

Description

The focus of this course is on the relationship between motion and friction. The motion of surfaces can vary in complexity, from simple steady sliding to movements that are highly variable in time and direction. Tribology is the study of such surfaces in relative motion and the performance of any tribological interface is directly related to friction. Depending on the desired outcome, the optimal friction may be either maximum or minimum. Tribology enables motion, and system designs rely on a proper understanding of the tribodynamics. This course provides the fundamentals of continuum tribodynamics modelling and simulation. In addition, novel non-invasive experimental techniques are introduced.
