Inductive Damping of Structural Vibrations
Vibrations in mechanical systems are often undesirable and can have consequences ranging from noise emission to system failure. In many technical applications, vibration dampers are therefore used to reduce structural vibrations. There are various approaches to achieve this. One modern approach is to use electromagnetic induction to convert the mechanical energy of the vibration into electrical energy. Thus, the electrical energy can be removed from the system, e.g. by converting it into heat in electrical resistors or by storing it in the sense of energy harvesting.
The aim of the research is to investigate networks of inductive damping elements and thus effectively suppress structural vibrations.
In order to build up a fundamental understanding of the interaction of electrics, magnetics and mechanics, various minimal models are systematically investigated using analytical methods.
On the basis of the examined minimal models, extended damping modules are then developed and examined with regard to their effectiveness. In this step, the adaptability of the modules to different environmental influences plays a particularly important role.
The developed modules will then be intelligently linked to achieve the most effective reduction of structural vibrations.
The knowledge gained will be validated during the project by means of tests and FE simulations.
