Components in every aspect of mechanical engineering consist more and more of electrical parts and are supplemented by actuators and sensors. The interaction between single components and their influence on the reliability of the overall system is the main area of research of the group. Starting from common methods of structural durability and reliability in mechanical engineering, new concepts for assessing the system reliability of complex adaptive systems are developed and verified. Together with the expertise in machine acoustics, this makes an ideal background for the development of adaptive systems for the reduction of noise emission, which is one of the main research topics of the group. All research work is carried out in close cooperation with the Fraunhofer-Institute for Structural Durability and System Reliability (LBF). The objectives of the LBF are to develop and enhance the fundamentals of design analysis and the optimization of complex structures and systems under service loading conditions. The aim is to develop and provide methods and procedures for the improvement of the design and manufacture of machinery, vehicles, industrial equipment, and buildings with regard to strength and fatigue behavior under service operational conditions, and with respect to material efficiency, system weight, and service life, as well as manufacturing, operation, and maintenance costs. Since products are becoming more and more complex, e.g., intelligent, active systems that combine electromechanical, electronic and informational components, research activity is currently being extended to the system reliability aspects of complex structures and systems. In this context, testing in a virtual environment is becoming more and more important in a products design process. There is a strong interconnection with the research areas of the proposed Graduate School. Particular benefit is expected from collaboration in the areas of multi-physics and multi-scale simulation for adaptive applications involving multifunctional materials such as piezoelectric ceramics or shape-memory alloys. Reliability assessment of these complex adaptive systems requires modeling techniques for distributed quantities such as degradation functions or tolerance distributions, and methods for simulation based optimization as they are an extremely important tool to handle the inherent complexity and fuzziness of the adaptive systems considered.
