MEC 402: Mechanical Vibrations. Credit 3. Modeling, analysis and design for mechanical vibrations. Fundamentals of free vibration, harmonically excited vibration and vibration under general forcing conditions are considered for one degree, two degree and multidegree of freedom systems; continuous systems; vibration design strategies including isolation and absorbers.

Pre-requisites: MEC 262 and MEC 363

Textbooks: Singiresu S. Rao, Mechanical Vibrations, Addison-Wesley

Course Objectives:

This course is designed to give seniors an understanding of methods of
modeling, analysis and design for mechanical vibrations of machines and structures, with applications made to a variety of engineering problems.

Topics:

1. Fundamentals of vibration; design for stiffness (5 class hours)
2. Free vibration of single degree of freedom mechanical systems; criteria for impulse modeling of response; design for time of response restriction (9 class hours)
3. Harmonically excited vibration (5 class hours)
4. Vibration under general forcing conditions; design for shock loads and earthquake conditions (8 class hours)
5. Two degree of freedom systems; coordinate coupling and principal coordinates; multidegree of freedom systems; orthogonality of modes; solution for free of forced vibration with principal coordinates (7 class hours)
6. Vibration control; design of vibration absorber (2 hours)
7. Continuous systems; lateral vibration of beams (3 hours)
8. Tests: 2 semester exams, final exam (4 hours)
