Course Goals:
This course is designed to give students an in-depth understanding of mechanical vibrations and the
necessary tools to measure, analyze and design related systems
Course Outcomes: After completing the course, students will be able to:
1. Model simple vibratory systems.
2. Determine equations of motion for idealized systems.
3. Solve equations of motion for single degree of freedom systems subject to harmonic, general periodic
and arbitrary forcing functions.
4. Explain the mechanisms of undamped and damped free and forced vibration of SDOF systems and the
physical meanings of phase in the response
5. Write equations of motion for idealized multi-degree of freedom systems.
6. Determine natural frequencies and mode shapes for systems with two and three degrees of freedom.
7. Determine free and forced response for systems with two and three degrees of freedom.
8. Explain degrees of freedom (DOF), forced vibration, free vibration, damping, natural frequency, modal
analysis, mode shapes.
9. Identify equipment used in experimental vibrational measurement (including accelerometers, proximity
probes, velocity probes, shakers, and a digital signal analyzer)
