Synopsis

The fundamental concepts of rigid body and particle dynamics taught in the second level dynamics unit will be further reinforced. This unit then focusses on mechanical vibrations theory. The methodology for analysing the response of a vibratory system to given external stimuli is covered. Both single and multi-degrees of freedom and discrete and continuous vibratory systems will be analysed. The methods for developing the equations of motion of a vibratory system using Newton's 2nd law and the Lagrange equation and the manipulation of these equations to analyse the free and forced vibration responses of these systems will be introduced. The analysis of forced vibrations will include periodic and non-periodic forcing functions.

Outcomes

Upon successful completion of the unit, students are expected to be able to :

Knowledge and Understanding:

  • analyze the kinematics and kinetics of particle and rigid body dynamical systems
  • employ vector analysis algebra in solving 3D engineering dynamics
  • employ the concepts of degrees of freedom and its use in defining a model and the solutions to the model
  • analyse the vibration response of a mechanical system subject to periodic and non-periodic forcing
  • outline the fundamentals of model analysis for multi-degrees of freedom dynamical systems

Skills:

  • explain the role of vibrations in machines and structures in engineering
  • explain how vibrations can affect the safe operation of machinery

Attitudes:

  • analyse dynamics and mechanical vibrations problems
  • breakdown the concepts of dynamics in the analysis of vibration problem.
  • devise appropriate measurement quantities for the analysis of vibration problems

Assessment
