Prerequisites by Topics:

1. Rigid Body Dynamics.
2. Free and Forced Vibration.
3. Vibration of Multidegree-of-Freedom Systems.
4. Dunkerley and Rayleigh Approximations.
5. Balancing and Whirling.
6. Fourier Series and Frequency Response.

Learning Objectives[^1]:

1. To develop students' competence in the use of experimental tools for problem solving and design in the area of dynamics and vibrations (1,2,6)
2. To provide opportunities for the students to practice communication and team-building skills, and to acquire a sense of professional responsibility, and to motivate and train the students to learn on their own (3,4,5).

Experiments: (Selected experiments from the following list)

1. Cam Dynamics.
2. Gyroscope and Gyroscopic Effects.
3. Free Vibration of a 1-DOF System.
4. Forced Vibration of a 1-DOF System due to a Rotating Imbalance.
5. Forced Vibration of a 1-DOF System due to an Oscillating Support.
6. Vibration Analysis Equipment: Forced Vibration due to an Applied Force.
7. Lateral Vibration of Beams (Dunkerley's Formula-Dynamic Absorber).
8. Torsional Oscillations of Rotors.
9. Torsional Oscillations of a Single Rotor with Viscous Damping (using Universal Apparatus).
10. Damped Transverse Vibrations of Rigid Beams.
11. Whirling of Shafts.
12. Balancing of Rotors: Static and Dynamic Balancing.
13. Balancing of Rotors using a Vibration Meter and a Phase Meter (Vibration Analyzer).
14. Torsional Vibration with Non-contact Laser Beam Transducer.
15. Introduction to Vibration Analyser.
16. Experimental Modal Analysis Using an FFT Analyser.
17. Machine Condition Monitoring and Signature Analysis.
18. Accelerometer and Vibration Level Calibration.
19. Random Vibration: Methods of Analysis.

Computer Usage:

1. For the experiments done, the students are required to use specialized software to acquire and analyse data, and to validate the results.
2. Design of Experiment: Student teams are to be given which require the use of computer tools introduced.
3. Laboratory reports are to be prepared by using appropriate computer-software (word processing, graphics, spreadsheets)

Evaluation:

1. Exams.
2. Quizzes.
3. Reports.
4. Oral presentation.
5. Self and Team Assessment.
6. Project.
7. Lab participation.
