Mechanical Vibrations (Forår 2013)

Kursuskode : ME-MEV-U1
ECTS Point : 5 Status : Tilvalg
Placering : 6. semester Timer pr. uge : 4
Længde : 1 semester Undervisningssprog : Engelsk

Hovedindhold : Equations of motion with initial conditions.

Vibrations of linear single-degree-of-freedom systems: Free and forced vibrations for translation and rotation. Viscous damped systems and vibration isolators.

Pendulums and mass moment of inertia.

Vibrations of linear two-degree-of-freedom systems: Free and forced vibrations. Vibration absorbers. Viscous damping.

Vibrations of continuous systems: Equations of motion for strings, bars and beams. Boundary and initial conditions. Eigenfunctions, eigenvectors and eigenvalues. Whirling shafts and Dunkerley’s formula.

Finite Element Methods: Mass and Stiffness matrices and equations of motion for bar and beam expressed in Matrix form.

Introduction to non-linear vibration.

The software “DAMA” will be used to generate computer simulations and animations in order to enhance the students’ understanding of the motion and vibration of mechanical systems.
Undervisningsform : The teaching is both project-oriented and problem-based, using realistic systems. There will be lectures. 4 assignments and a project based upon experiments with Frequency Analyzer must both be handed in. MATLAB simulation will be use in the project.
