Goals:
Overall Educational Goal:
The objective of this course is to teach seniors basic methods and concepts in vibration analysis and to give a brief overview of techniques used in vibration isolation and absorption.
Specific Instructional Goals:
1. Develop skills for the analysis of oscillatory systems and the reduction of continuous structures into lumped parameter systems.
2. Develop a basic understanding of degrees of freedom (DOF) resonance, natural frequencies, and the effect of various types of damping.
3. Develop a working knowledge of harmonically excited and general forced vibration.
4. Introduce vibration concepts in multi-DOF and continuous systems.
5. Show use of multibody and finite element software in vibration analysis and visualization; introduce the use of numerical methods in vibration analysis.
6. Provide a survey of vibration control and mitigation methods.
Course Topics:
1. Introduction and definitions
2. Free and force oscillations of one-DOF systems
3. Harmonic and general forced vibrations of one-DOF systems
4. Free and forced vibrations of two-DOF systems
5. Multi-DOF systems
6. Natural frequencies and mode shapes
7. Vibration control methods
8. Vibrations measurement methods
9. Continuous systems
Class Requirements:
1. Three lecture sessions per week.
2. Approximately five homework problems per week. Homework assigned each Friday, due by 4:30 pm the Friday of following week. No late homework accepted. [20 percent of grade].
3. Two midterm examinations (September 26 and November 7) [25 percent each] and one final examination (11:00 am-1:00 pm, December 7 ) [30 percent]. A project may be assigned instead of a final exam. No makeup examination will be given.
Computer Usage:
Students are introduced to the use of MATLAB in vibration analyis and get an overview of finite-element procedures using ANSYS in the analysis of continuous systems.
Laboratory Projects:
None.
Assessment of Course Goals:
Through examination and homework grades.
