Continuous systems: free & forced vibration, modal analysis, approximate techniques, finite element method. Advanced topics: vibration measurement techniques, nonlinear phenomena, demonstration project.

Learning Objectives
After successfully completing this course you should be able to:

1  UNDERSTAND AND APPLY DISCRETE, MULTI-DEGREE OF FREEDOM, SYSTEMS VIBRATION THEORY
1.1 Revise modelling using Lagrange’s equations and understand how to obtain linear equations of motion in matrix form.
1.2 Solve for undamped natural frequencies and mode shapes of two degree of freedom and multiple degree of freedom systems.
1.3 Understand modal analysis of discrete systems, including orthogonality of modes and use direct and modal solutions to forced vibration problems.
1.4 Apply the theory to engineering applications involving free and forced vibration, such as dynamic vibration absorption, torsional systems, coupled translation/rotation and damped motion.
1.5 Understand and use computer packages to solve multi-degree of freedom vibration problems.

2  UNDERSTAND AND APPLY CONTINUOUS SYSTEMS THEORY
2.1 Model and analyse the fundamental types of continuous systems vibrations including transverse string, axial, torsional and beam vibrations and use them to determine natural modes of vibration for engineering applications.
2.2 Model and analyse the forced vibration of beams and orthogonality and apply them to solve engineering applications.
2.3 Derive and understand approximate methods including Rayleigh's Energy, Dunkerley’s, Holzer and Finite Element Methods and apply them to solve more complex problems in engineering.
2.4 Understand and use a finite element computer package to extend fundamental concepts to solve complex multi-beam and plate engineering problems.

3  UNDERSTAND AND APPLY ADVANCED TOPICS IN DYNAMICS AND VIBRATIONS
3.1 Understand vibration measurement and instrumentation and perform experimental modal analysis on a structure.
3.2 Understand and apply signal processing using fast Fourier transforms.
3.3 Understand extended dynamics and vibration concepts such as likely nonlinear phenomena.
3.4 Understand how the course material is applied in industry.
3.5 Demonstrate via physical and or simulation model and report on a concept or application in advanced dynamics and vibrations.
