assoz. Prof. Dipl.-Ing. Dr. Thomas Furtmüller, +43 512 507 61617

Course number:

844523

Title:

UE Measurement in Structural Dynamics

Type/hours:

UE 2

ECTS credits:

2,5

Period:

Block

Mode of repetition:

each semester

Language of instruction:

German

Learning Outcome:

Understanding of experimental modal analysis
Further understnading of frequency domain methods in structural dynamics
Knowledge of basics of signal processing and its importance in measurement technology

Contents:

Repetition modal analysis, extension to non-classically damped systems
Repetiton frequency domain methods and extension with respect ot experimental modal analysis
Fourier analysis (Fourier series, Fourier transformation, discrete Fourier transformation)
Device-specific basics (impulse hammer, piezoelectric acceleration sensor)
Basics of digital signal processing (sampling, discretization, aliasing, leakage, filters, windows)

Methods:

Theory: Theoretical basics are made available via online videos (starting ca. in november, once basics have been discussed in the class Structural Dynamics 1). Office hours are available online (BigBlueButton) for answering questions.
Pratice: After positive evaluation of an intermediate test an experimental modal analysis of a structure/strucural part is conducted. Work in groups of 3 under supervision of the course leader (starting ca. in january).

Assessment:

Writing of test reports. Final oral examination.

Literature:

Printed course material

Prerequisites:

Attendance of the class “Structural Dynamics and Earthquake Engineering 1”

eLearning shares:

eLearning (e.g., partly virtual, videoconferencing, ...)

Remarks:

Compulsory registration
