Engineering Models in Structural Dynamics and Vibroacoustics

After a successful participation in the course, the students are able to analyze structures for dynamic problems defining engineering models and suitable substructures with clear interfaces. Students apply various methods for solving the respective differential equations and discuss the solutions regarding dynamic characteristics. Students can evaluate the methods and their applicability for modeling in the low-, mid- and high-frequency range.

The content of the module is the modeling of structures in the field of civil engineering and mechanical engineering for dynamic problems. Interfaces and subsystems are defined for a product in the appropriate manner described by differential equations. Impedances and transfer functions are determined and aspects of insulation and damping are discussed. Measures like elastic support and damping aspects are explained. The effectiveness of measures at interfaces is explained via the measure of insertion loss. Modeling techniques for different frequency ranges are discussed, where the limits of the individual model are discussed using wave approaches.
