Sound and Vibration Laboratory

The Institute of Technical Mechanics focuses on experimental and numerical methods of mechanics. Both in teaching and in basic and applied research, a sound and vibration laboratory is available for this purpose.

The aim of the laboratory is to facilitate experimental investigations in teaching and research in order to reconcile newly developed simulation methods and results and to carry out the identification of missing parameters, which can often only be determined experimentally.

In engineering practice, a balanced cooperation with research institutes, companies and industrial partners is desired in order to be able to apply the existing expertise as quickly and successfully as possible. In this context, the institute offers a collaboration for companies and industrial partners in order to jointly develop solutions for research projects with special challenges in the field of sound and vibration as well as finite element computations and multi-body simulations.

The existing workplaces also provide students with an optimal environment for experimentally acquainting themselves with the diverse phenomena of vibration theory in small groups. For the participants (internship participants, bachelor students, diploma students, doctoral students) it is possible to learn and use modern solutions in the field of sound and vibration measurement independently, but under professional supervision. During the practical lessons, it is also important to use and compare different solutions offered in the market in the field of sound and vibration measurement technology.

In order to be able to use the measurement systems, there are a large number of sensors (laser path measuring sensors, inductive displacement sensors, acceleration sensors, free-field microphones, microphone array, intensity probe, tachometer, force sensors, strain gauges, etc.) and actuators (electrodynamic shakers, piezoelectric actuators, impact hammers, etc.) available.

The combination of the latest hardware and supplied software environments allows a large part of the occurring measuring tasks in the field of structural testing (linear and nonlinear dynamic systems) as well as operational vibration tests (eg: order analysis, machine diagnostics) to be performed optimally.
