Applied Vibration Engineering

Module aims

This module teaches students how to use the theoretical principles of vibration, and vibration analysis techniques, for the practical solution of vibration problems. It builds on students’ prior knowledge of vibration theory, and concentrates on the applications. A key feature is that students work on identifying and defining the problems to be solved, prior to solving them. This includes choices of assumptions, choices of measurements to be made and information to be investigated, and choices of analysis techniques to be employed. 

ECTS units:  5

Learning outcomes

On successfully completing this module, students will be able to: 

1. Describe the nature of real vibration problems in engineering and their unwanted results

2. Explain the operating principles of common vibration measurement tools and of signal analysis techniques

3. Describe the principles of the advanced vibration modelling and analysis techniques, e.g. frequency response functions and Finite Element analysis

4. Analyse a vibration problem to identify and model its principal features

5. Estimate, from this analysis, a numerical solution (using simplified hand calculations where possible) and an assessment of its validity

6. Propose a strategy for the solution of a practical vibration problem

7. Take measurements using force hammers, accelerometers, noise meters and spectrum analysers

8. Prepare a Consultant-Client report and presentations, keeping a logbook of all practical work

Pre-requisites

ME2-hDYN  Dynamics, or equivalent course elsewhere.

Teaching methods

1 x 1h/week lectures on theory and analytical methods. Several lectures include practical demonstrations. The lectures follow a developing sequence, covering the key aspects of problem identification, theoretical and experimental tools for understanding the problems, and strategies for solutions. During term 2, two of these lecture slots will be used to provide assistance with group projects and tutorial sheets. Students also complete a  small group Consultant-Client project where they tackle a real vibration problem, playing the roles of consultant and client. This is done in some of the lecture periods, plus some extra periods (about 5-8 hours) scheduled to fit with student's other timetable commitments, and also in students' own time.
