Active Vibration Damping

Goals

The students study the basics of vibration dynamics, among other things the derivation of equations of motion, the modal uncoupling and stability analysis.


Different techniques are presented for the protection against vibration. Apart from the source and the receiver isolation also the design of dynamic vibration absorbers is studied.


Furthermore active systems are studied for vibration damping on the basis of applications, for example an active engine bracket. In particular piezoelectric actuators are studied more precisely.


The signal analysis as well as the experimental modal analysis represent a further emphasis.

Topics

  • Description and characterisation of vibrations

  • Design of vibration absorbers
  • Status monitoring
  • Observer design
