ME 4600-431: Mechanical Vibrations
What to Know |
|
|
| Goal: |
|
What can we understand about the behavior of
mechanical systems in terms of the parameters such as mass,
damping, and stiffness? Specifically, how do the structure and
parameters of a mechanical system affect its dynamical
behavior? |
|
|
| Requirements: |
|
This class requires the following knowledge:
- Dynamics (basic concepts of kinematics and kinetics)
- Linear Algebra (vectors, dot products, cross products, etc.)
- Differential Equations
|
|
|
| Results: |
|
Put it all together. Use dynamics to model a
physical system and differential equations to find the resulting
behavior.
In general, to solve any linear differential equation we assume
a solution and then "make it fit". This results in a
characteristic equation, whose solution determines characteristics
of the system, such as frequency of oscillation and decay
rate.
When this class is over, you should understand the following concepts:
- Degree-of-freedom
- Single degree-of-freedom systems
- Modeling-Momentum balance
- Free vibration-assumed solution
- Forced vibration
- Multi degree-of-freedom systems: the behavior of an
n-dof system is determined by n 1-dof
equations. Compare a single-mode solution with general
behavior.
- Modeling-Lagrange's equations
- Free vibration
- Forced vibration

| Outcomes: |
|
This course is expected to address the following
highlighted ABET outcomes:
- Apply energy,
momentum, continuity, state and constitutive
equations
- Design and perform laboratory
experiments for thermal, fluid and mechanical systems to
gather data and test theories.
- Design thermal, fluid,
mechanical and control systems
- Participate effectively
in same-discipline and cross-disciplinary groups
- Identify, formulate,
and solve thermal, fluid, and mechanical engineering problems
by applying first principles, including open-ended
problems
- Develop practical
solutions for mechanical engineering problems under
professional and ethical constraints
- Communicate effectively
with written, oral, and visual means
- Recognize the fact that
solutions may sometimes require non-engineering
considerations such as art and impact on society.
- Be prepared for a lifetime of
continuing education.
- Recognize environmental
constraints and safety issues in engineering
- An ability to use
modern modeling and simulation techniques, and computing
tools
The complete list of ABET outcomes and objectives for the ME program
is also
available. |
