Overview

Mechanical vibration is an important consideration for the performance, functionality and integrity of many structures and machines. This unit of study critically reviews theoretical concepts related to mechanical vibrations. It is designed to promote the requisite knowledge, skills and competencies to analyse and resolve vibration issues across a broad range of applications. Students’ learning is consolidated through real world projects specifically designed to enhance their classroom and laboratory-based learning.

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; single, two and multi degree-of-freedom systems; mode shapes; vibration measurement and instrumentation; random vibration analysis; and modal parameter estimation.

Learning Outcomes

On successful completion of this unit, students will be able to:

  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. Construct numerical models of vibratory systems such that they can be used to predict and enhance performance;
  4. Compute and predict the vibration behaviour of complex systems (including two and multi degree-of-freedom) using vibration theory;
  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.
