Dynamics III

Mechanical systems


Contents

The lecture Mechanical Systems - Dynamics III expands particular parts of the previous curriculum Dynamics I and II. A major focus of the course is formed by the damping matrix in general form and further, previously untreated components of the differential equation for linear vibrations of multi-degree-of-freedom systems.  Superordinate aspects such as system stability, identification, and model reduction are also considered:

 
  • General system aspects,
  • material models and damping,
  • complex vibration modes,
  • mass dampers,
  • modal analysis,
  • gyroscopic und zirkulatory forces,
  • model reduction.

The aim of the lecture is to expand the methodological repertoire for the treatment of vibration problems. On the one hand, this specifically concerns the origin and effect of damping. On the other hand, a general understanding of dynamic systems should be achieved. This facilitates to establish a connection to other areas, such as for example experimetal methods, control theory, flight mechanics and adaptive structures.
