Aim
The aim of the course is to:
- provide knowledge of the theory of small oscillations of
undamped and damped mechanical systems with multiple degrees of
freedom for discrete systems and continuous systems.
- give an understanding of the theory of wave propagation in
elastic materials.
Learning outcomes
Knowledge and understanding
For a passing grade the student must
- be able to give an account of the most important results in the
theory of small oscillations in undamped and damped mechanical
systems.
- be able to formulate and analyse theoretical models for small
oscillations in n-degree systems as well as in some simple
continuous systems.
- be able to apply modal and transient analysis.
- be familiar with the principles of experimental modal
analysis.
Competences and skills
For a passing grade the student must
- be able to analyse certain simple mechanical systems with the
aid of computer programmes (Mathcad, FEM).
- be able to perform an analysis of a vibration problem and to
present the results in a well-written report.
- be able to describe some technical problems and possibilities
of mechanical vibrations in industrial applications.
Judgement and approach
For a passing grade the student must
- be able to evaluate technical solutions, for
instance vibration isolation and damping of vibrations.
- be able to evaluate achieved results based on the problem
formulation at hand as well as physical limitations.
