1. Course Aim
Main Aim
Sub-Aims
The main aim of this course is to study the oscillatory nature of
mechanical systems so that we may design such systems with
knowledge of their vibratory response
After successfully completing this course, the student will be able to:
1) Perform detailed analysis of the response of one , two and multi
degrees of freedom systems in both free and forced vibration regimes
2) Demonstrate knowledge of simple methods of vibration control
3) Explain the interaction of mechanical vibrations with humans
4) Effectively communicate engineering work by oral and/or written
means
5) Perform vibration design of simple mechanical systems that can be
approximated by one , two or multi degrees of freedom systems.
2. Course Content
Free Vibrations, Single Degree of Freedom Undamped and Damped Systems.
Forced vibrations with applications - Systems with Two – Degrees of Freedom –
Vibration Absorbers. Numerical Methods for Multi – Degrees of Freedom Systems.
