The unit incorporates the following topics: Fundamental vibration theory; various types of damping; response due to initial conditions (free vibrations); harmonic and complex forcing functions; Fourier analysis and the Fourier spectrum; Shock Response Spectrum; single, two and multi degree-of-freedom systems; mode shapes; vibration measurement and instrumentation; random vibration analysis; and vibration absorbers and vibration control.
NEM3101 - Engineering Analysis and Modelling
|1.||Map and articulate the fundamental concepts of mechanical vibrations and justify their application in a variety of engineering design contexts;|
|2.||Measure and analyse the salient vibration characteristics of vibratory systems such as structures, machines and vehicles;|
|3.||Develop numerical models of vibratory systems such that they can be used to predict and enhance performance;|
|4.||Use vibration theory to calculate and predict the vibration behaviour of complex systems (including two and multi degree-of-freedom);|
|5.||Analyse the vibration behaviour of structures and machines taking into account economic, industrial, human and environmental considerations; and|
|6.||Produce accurate, clear and coherent technical reports on the vibratory behaviour of structures and mechanical systems for a variety of audiences.|
|Test||Weekly Quiz. The quizzes, to be undertaken individually, will be based on the lecture material and specific reading material.||10%|
