Vibration Control

Vibration Control. Instructor: Prof. S. P. Harsha, Department of Mechanical and Industrial Engineering, IIT Roorkee. The main objective of course is to present fundamentals to a modern treatment of vibrations, the control strategies using active and passive control methods. In this course, the design consideration of material selection, smart materials and vibration measurement techniques are also discussed. Topics covered in this course include Basic vibration control, Vibration isolation, Vibration generation mechanism, Passive vibration control, Active vibration control, and Vibration measurement.
