starting in the academic year 2012-2013

TAM 5700Intermediate Dynamics(Fall) andare cancelled.

MAE 4770/5770Vibrations(Spring)They are replaced by two new re-organized courses.

Together, the two new courses will cover about 2/3 of the vibrations material from the former MAE 4770/5770, all of the core dynamics material from the former TAM 5700, some of the material from previous robotics and modeling courses, and a bit more multi-object dynamics than has been taught before. Here are the official descriptions of the new courses.

1) MAE 4735/5735:Intermediate Dynamics and VibrationsFall, MWF 10:10-11, Instructor for fall 2012: Ruina

The course emphasizes the dynamics and vibrations of multi-degree-of-freedom systems including particles, rigid-objects and structures. Introduction to Lagrange's equations. Finding equations of motion, solving analytically and numerically; graphical presentation of solutions. Conservation laws. Modal analysis of discrete and continuous systems. Damped and undamped systems. Vibration absorbers and vibration control for discrete systems.

Prerequisites: Math 2940, MAE 3260 or equivalents, or permission of the instructor.

For more details see this the MAE 5735 www page.

2) MAE 6700:(anticipated, not yet officially listed)Advanced DynamicsSpring. 3 credits. Instructor for Spring 2013: Ruina

Advanced dynamics of particles and rigid objects with emphasis on 3 dimensions and complex multi-object systems. Topics include: Hamilton's principle, Lagrange equations, dynamics of mixed lumped and discrete systems. Raliegh-Ritz method, stability theory, and approaches to multi-object systems. Examples will come from celestial mechanics, machines, robotics and vehicle dynamics.

Prerequisites: MAE 5735, or equivalent, or permission of the instructor.

In any case you should check with your advisor. Here are some guidelines.

You are a PhD student with a major interest in Dynamics:

You should take both of these classes (unless you already know the material).

You are a PhD student with a minor interest in Dynamics:You should take at least one of these classes.

You are an M-Eng student with a major interest in Dynamics:

You should take at least one of these classes.

You are an M-Eng student with a minor interest in Dynamics:

You should take at least one of these classes.

You are an undergraduate:

If you like and are good at dynamics, and have place in your schedule, you should take the first of these courses (4735). Then consider continueing on (6700) if you are somewhat advanced.

Because of retirements, changes of faculty and departments merging, the dynamics course offerings have evolved without restructuring for several years. Here are some of the issues that the new course sequence is intended to address while also making a coherent 2-course sequence.

* The

Modeling and Simulationcourse from years ago had good material that should be taught, but that course is no longer being taught.* The only dynamics course now between TAM/ENGRD 2030, Sophomore

Intro to Dynamics, and the former TAM 5700,Intermediate Dynamics, was MAE 3260System Dynamicswhich is largely about linear systems rather than (=Fm) mechanics.a* Undergraduates with machines/mechanisms/robotics/bio-dynamics interests could use and enjoy a more advanced dynamics course than TAM 2030 but not so advanced as TAM 5700 sometimes was.

* MAE 4170/5170,

Introduction to Robotics Dynamics, Control, Design, is no longer being taught, but has some material that should be taught.* For graduate students in Dynamics there is a need for multi-object dynamics that goes past the usual coverage of TAM 5700.

* Some entering students M-Eng students have found that the former TAM 5700 started at too high a level, while some entering PhD students found that it starts at too low a level.

* There seems not to be a need for a full semester on Vibrations.

* There was been some overlap between

Vibrations(MAE 4700) andIntermediate Dynamics(TAM 5700).
