Research group System Reliability, Adaptive Structures, and Machine Acoustics

Our profile areas

Reliability

Components in all areas of engineering are increasingly equipped with electronic components and supplemented by actuators and sensor elements. The traditional designs are combined to form complex systems with multiple features. The interaction between single components and their influence on the reliability of the overall system is currently not well understood and is the main area of research at SAM. Therefore, based on common methods of structural durability and reliability in mechanical engineering, new concepts for assessing the system reliability of complex systems should be developed and verified. In addition to the development of basic principles, methods, and techniques, their application to manifold problems in mechanical engineering will be considered.

Adaptive Structures

Adaptive Structures is a structural technology which enables the monitoring and enhancement of the mechanical properties of products with the help of advanced methods of structural dynamics and signal processing, and through integration of novel sensors and actuators. Adaptive Structures focuses specifically on vibration technology, light-weight design, and functionality.

Machine Acoustics

In Machine Acoustics the creation, transmission, and radiation of sound is treated using the model of the fundamental equation of machine acoustics. In doing so, direct and indirect sound radiation must be distinguished. In direct sound radiation, airborne noise is created directly by a machine. Contrarily, in indirect sound radiation the structure is initially excited to vibrate (structure-borne sound) and then emits airborne sound over its surface. Therefore, in addition to the emission and propagation of airborne sound, the work at our Research Group also includes the creation and propagation of structure-borne sound. More recently, adaptive systems are being used in acoustics that are aimed at reducing the noise (active noise control) or changing the noise (sound design).
