8 credits, NQF Level 7


The module discusses the vibration elements of engineering in machinery operation. The emphasis is on the formulation of dynamic models of typical mechanical systems in the context of single and multi-degrees of freedom. Discrete models also form part of vibrational analysis because of their effectiveness. Of particular importance are the governing equations for vibrational analysis under steady and transient conditions. Standard numerical solutions from the mathematics are used for the purpose of analysis with the   focus being in the correct interpretation of results for design application. The vibration measuring and monitoring process is also an important element of analysis.


On completion of the module, students will be expected to be able to:

1Understand the concept of vibration in mechanical engineering
2Formulate dynamic models of typical mechanical systems
3Formulate the appropriate equations for vibration analysis
4Solve the vibration problems by employing suitable equations
5Apply vibration analysis techniques

Workload requirements

Uncontrolled vibrations in machinery are one of the main causes of catastrophic failure of machine components. The measuring and correct diagnostics of vibration related problems can provide an early warning of imminent failure of mechanical components, particularly the rotating parts. The application of vibration analysis in machine design will enhance the life expectancy of machinery when in service. There will be a combination of lectures, that will include interactive elements. All outcomes will be assessed by means of class tests and a final examination.
