Learning outcomes
After successfully completing this course you should be able to:
LO1.
Apply discrete systems vibrations theory - Model lumped parameter (i.e. discrete) systems using Lagrange's equations to obtain linear equations of motion in matrix form.
LO2.
Apply discrete systems vibrations theory - Undertake modal analysis of multi-degree-of-freedom (MDOF) systems to determine natural frequencies and mode shapes (including orthogonality of modes) and then use these in direct and modal solutions to forced vibration problems.
LO3.
Apply discrete systems vibrations theory - Model and analyse free and forced vibration problems for lumped-parameter (i.e. discrete) systems, including dynamic vibration absorption, torsional systems, coupled translation-rotation, and damped motion.
LO4.
Apply continuous systems vibration theory - Model and analyse the fundamental types of continuous system vibrations, including transverse string, axial, torsional, and beam vibrations, and use modal solutions to determine the natural modes for free and forced vibration for engineering applications.
LO5.
Apply continuous systems vibration theory - Use approximate methods, including Rayleigh's Energy, Dunkerleys, Holzer, and finite element methods, for the solution of practical engineering vibration problems.
LO6.
Apply continuous systems vibration theory - Apply engineering software to analyse the vibration of discrete multi-degree-of-freedom systems and continuous multibody (e.g. beams and plates) systems.

Implement measurements and applications in dynamics - Use vibration measurement and instrumentation to perform experimental modal analysis on mechanical systems.
LO8.
Implement measurements and applications in dynamics - Understand and quantify the effects of non-linear behaviours on modal analysis.
