Linear Vibrations

Peop­­le in char­­ge

Prof. Dr.-Ing. Hartmut Hetzler (Lecture)          Mitja Rosenboom, M.Sc. (Exercise)


Many vibration problems in engineering can be described in a very good approximation by linear differential equations, so that the theory of linear differential equations, which is very well developed in terms of mathematics, can be applied.

The lecture shall give an introduction to common methods for the treatment of linear dynamical systems. First, general vibration systems with N degrees of freedom are treated. Then the dynamics of systems in state space will be discussed.

The lecture continues the En­gi­nee­ring Vi­bra­ti­ons and serves as preparation and basis for further courses, especially Nonlinear Vibrations.
