Course Learning Objectives:

By the end of the course the student will be to:

1. Model linear and nonlinear mechanical systems as combinations of springs, masses and dampers.

2. Determine and define the degrees of freedom of a given mechanical system.

3. Extract the equations of motion of a given mechanical system.

4.  Analyze and interpret the response of mechanical systems to various types of excitations.

5.  Analyze and interpret the response of mechanical systems to different cases of damping.

6. Predict qualitatively the response of systems based on the spectral content of the excitation.

7.  Minimize the effects of transient and harmonic excitations on systems and their support structures.

8. Decouple equations of motion

9. Understand the significance of vibration control in various applications

Lab. report:

• Work with others is encouraged, but turn in your own team efforts (no copying)
• No late Lab. report will be accepted

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 the topics
• Do the homework daily so you can ask questions in class
• Use you resources for help (classmates, upperclassmen, faculty, the library)

Prerequisites by Topic:

1. Students should be familiar with free and forced vibration of Single Degree Of Freedom (SDOF) systems.
2. Students should be familiar with the kinematics and kinetics of two and three-dimensional rigid bodies.
3. Students should have a good understanding of the mechanics of solids including the ability to determine effective spring constants of common structural members.
4. Students should be able to solve linear ordinary differential equations.
5. Students should be familiar with concepts from linear algebra including matrix vector arithmetic, determinants, matrix inversion, eigenvalues, and eigenvectors.
6. Students must have the ability to formulate and solve problems using MATLAB.
