How to Succeed

 

  • Accept that it is your responsibility to learn the material (in spite of the book or teacher)
  • Show up and become engaged with your team and the topics
  • Continuously do homework preparation in advance  so you can ask questions in class
  • Use you resources for help (classmates, upperclassmen, faculty, the library)

 

Course Learning Objectives:

Conceptual:

  • To provide a background to the principles of vibration.
  • To deliver the fundamentals of Fast Fourier Transform (FFT) analysis.
  • To give an insight into the principles of monitoring and measurement.
  • To develop and understanding of maintenance categories.
  • To look into some depth at engineering solutions.

 

Specific (CLO according to ABET EC2000):

By the end of the semester, the students will be able to:

  1. analyze the free and hormonally excited vibratory systems.
  2. use  Fast Fourier Transform (FFT) to study the system performance with periodic excitation.
  3. classify transducers for vibration measurement.
  4. identify problems of vibration measurements and analysis: FFT analyzer, filtering, sampling, aliasing, averaging, windowing.
  5. distinguish between the four maintenance categories.
  6. identify the causes of machine problems using vibration analysis like: imbalance, misalignment, bearings, gears, fans, resonance, looseness, etc.
  7. function in a team.
  8. communicate effectively.
  9. search and collect necessary information from different resources
