Praktikum Strukturdynamik (Modul MW2296) (Praktikum)

Teilnahmekriterien & Anmeldung

Lernziele

After following this course, the student will be able • to understand how a Finite Element computer program is structured and what steps are needed to solve different structural vibration problems. • to apply the theory of Finite Elements and to build a discretized model • to evaluate what structural analysis steps are required to solve different types of dynamic problems (free vibration, harmonic response, transient dynamics) • to apply the appropriate numerical algorithms to solve the dynamical problems efficiently

Beschreibung

• Finite Element for vibration analysis: summary • Free vibration modes and eigensolvers • Mode superposition • Structures under harmonic excitation • Transient dynamics • Damping in structural dynamics • Model reduction • Sensitivity analysis

Inhaltliche Voraussetzungen

The student must have a solid background in Finite Element modeling and numerical methods for dynamics (e.g. Structural Dynamics or Engineering Dynamics).

Lehr- und Lernmethoden

The lab will include some theoretical explanation and some hands on exercises using MATLAB. The theoretical explanation will outline aspects necessary for the efficient handling of structural dynamic models. In the hands on exercises the student will program himself in MATLAB a simple Finite Element code to solve simple frame structures.

Studien-, Prüfungsleistung

In this course, the student will learn how the discretization of structural dynamic problems is programmed and how commercial codes can be used to efficiently compute the dynamic response of structures. It is assumed that the student has good basics in Finite Element methods and numerical techniques for vibration analysis (such as for instance lectured in Structural Dynamics MW2136). The lecture will mix advanced theory and computer exercises where the student will be asked to build and solve dynamic models, and to write work-reports. The grade will be based for 30% on the work-reports produced during the semester, and for 70% on the final oral exam where the student will be questioned on the content on his work reports.
