PERMAS workshop Dynamics II - Online (DYN-2-online)

Advanced Applications

In the training course Dynamics II, the solution methods of the basic course Dynamics I are dis-cussed in more detail and augmented by further techniques. At first, further options for the computation of eigenfrequencies and mode shapes are ex-plained. Especially the MLDR method is very useful, as it allows much faster computations in many cases. The mode shapes used for transformation to modal space can be complemented by additional basis vectors, so called addmodes. The different kinds of addmodes and their influence on the results are discussed. The definition of damping already addressed in the course Dynamics I is covered in more de-tail, such that the participants get an overview of the different ways to define damping in PERMAS. Assembly situations, which are often used in customers’ applications, as well as nonstructural mass is introduced. A large chapter deals with the primary and secondary results of the analy-sis procedures, including their interpretation. Moreover, the special analysis methods of Steady State Response and Spectral Response are discussed. The use of files to save intermediate results is shown. The training finishes with a short overview of further analysis method in dynamics, which are presented in special courses in detail. 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 par-ticipate online.
