Kursspecifika förkunskaper

Basic knowledge in dynamics, vibration and motion control.

Recommended but not mandatory are courses in Applied structural dynamics, Applied mechatronics, Rigid body dynamics, Digital control, Applied signal processing, Sound and vibration measurement, Active noise control.


The course aims at providing knowledge on modern methods and concepts of passive, semi-active and active vibration control, to cross the bridge between the structural dynamics and control engineering, while providing an overview of the potential of smart materials, (magnetorheological fluids, magnetostrictive materials, and piezoceramics), for sensing and actuating purposes in active vibration control. Vibration control applications appear in vehicle engineering, high precision machines and mechanisms, robotics, biomechanics and civil engineering. The focus of the project part of the course is on experimental validation of practical methods, i.e., methods that were found to actually work efficiently for passive and/or active vibration control. The course prepares students to use industry-leading data acquisition hardware and software tools for measurement, signal processing and vibration control.
