PERMAS workshop Dynamics (German) (DYN)
Dynamics Basics
The training course dynamics I offers an overview of the basic capabilities of PERMAS in dynamics.
A simple single degree of freedom system is used for a short introduction into dynamics, which is then extended to finite element models. After this, the course discusses the definition of density and mass, which is compulsory for analysis in dynamics.
A major part of the training course is modal analysis, i. e. the computation of eigenfrequencies or natural frequencies and the matching mode shapes. The influence and the treatment of rigid body modes is discussed in detail – this allows for the computation of unsupported systems.
The second part of the training course deals with the analysis of vibrating systems which are excited by external loads. Procedures for the response computation in time and frequency domain offered by PERMAS are introduced. The definition of loads and damping, choice of important parameters for the computations and the interpretation of results are discussed.
The training course is completed by an introduction to modal transformation and the subsequent response computation in modal space.
Finally, a short overview of matching examples and further training courses in dynamics is given.
All topics of the training course are complemented by short exercises using simple but realistic examples, which can be executed at the computers in our lecture room or at home if you participate online.
