16-Introduction to Damping (Half-Day, Hybrid)
Dr. Samir Nayfeh (Physical Precision LLC)

Tuesday, November 5, 2024 (1:30 PM – 5:30 PM)

The outline for this course is as follows:

1. Assessing vibration and its impact on performance:
   -How to interpret measurements of vibration
   -How to interpret FEA and make some basic estimates
   -Vibration impact on controllers
   -Vibration impact on performance

2. Energy dissipation mechanisms:
   -Joints
   -Materials
   -Friction
   -Eddy currents
   -Active dampers

3. Design of damping treatments in the structural loop:
   -Constrained layer dampers
   -Strain energy, relative stiffness, and design using FEA
   -Some examples of construction

4. Vibration reduction using reaction masses:
   -Modal mass and kinetic energy
   -Tuned and not-tuned mass dampers
   -Some examples of construction
   -Particle and impact dampers

Samir Nayfeh has over 30 years experience in the design of precision machines, with an emphasis on system dynamics and mechatronics. He received his B.S. and M.S. degrees from Virginia tech and Ph.D. from MIT. He served on the faculty at MIT from 1998-2006, publishing primarily on vibration damping and control. Since 2006, he has worked as consultant and co-developer to a variety of clients in development of precision machines. His current interests include system dynamics, mechatronics, flow, and tribology.
