General Vibration Systems

Vibration occurs in all rotating machines and is often unwanted or even disturbing. Passive countermeasures such as vibration attenuation or isolation using springs and dampers offer only limited performance and introduce unwanted weight. For this reason, we focus our research on systems with insight on the active vibration control, which show the capability of outperforming purely passive approaches by far.

The consideration of active measures already at the beginning of the product development does not only have the potential of replacing passive measures, but additionally results in the possibility of generating an improved overall system. This can be reflected for example on costs, weight and efficiency: on the one hand passive measures are discarded and on the other hand vibrations can be effectively affected by active systems, thus allowing for reduced requirements for the design of the basic passive system.

The knowledge about the basic passive system is the most important factor for the development of an active system, when aiming for an optimal solution of a specific problem. That is why the research group General Vibration Systems focuses on fundamental research regarding system knowledge. This covers for example the description of vibration in gearboxes and rotors, and identifying excitation sources and their influence on fatigue or failure. Throughout the consideration of the gained overall system knowledge within the design process and the control of an active system, a more efficient and performant system can be obtained compared to using standard methods.
