Vibrations are oscillations which repeats after equal interval of time in mechanical dynamic systems.
Although any system can oscillate when it is forced to do so externally, the term “vibration” in mechanical engineering is often reserved for systems that can oscillate freely without applied forces.
Sometimes these vibrations cause minor or serious performance or safety problems in engineered systems.
For instance, when an aircraft wing vibrates excessively, passengers in the aircraft become uncomfortable especially when the frequencies of vibration correspond to natural frequencies of the human body and organs.
Hence the objective of the course are
1. To understand the Fundamentals of Vibration and its practical applications.
2. To understand the working principle and operations of various vibration measuring instruments.
3. To be creative problem solvers whilst dealing with machinery involving periodic phenomena.
In this course the topics are covered to fulfil the above objectives and also at the end of this course students will be able to
CO1 : Define the basic terms of vibrating system
CO2 : Illustrate and identify the basic components of vibrating system
CO3 : Formulate mathematical models of problems in vibrations using Newton's
second law or energy principles
CO4 : Determine a complete solution to mechanical vibration problems using
mathematical or numerical techniques
