| Course code : | ME-MEV-U1 | ||
| ECTS Credits : | 5 | Status : | Optional |
| Placement : | 6. semester | Hours per week : | 4 |
| Length : | 1 semester | Teaching Language : | English |
| Principal Content : | 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. |
