About Fraunhofer
Fraunhofer is Europe’s largest application-oriented research organization. Our research efforts are geared entirely to people’s needs: health, security, communication, energy and the environment. As a result, the work undertaken by our researchers and developers has a significant impact on people’s lives. We are creative. We shape technology. We design products. We improve methods and techniques. We open up new vistas. In short, we forge the future.
The Fraunhofer-Gesellschaft undertakes applied research of direct utility to private and public enterprise and of wide benefit to society. The Fraunhofer-Gesellschaft is the largest organization for applied research in Europe with more than 80 research units, including 60 Fraunhofer Institutes, at different locations in Germany. The majority of more than 20,000 staff are qualified scientists and engineers with €1.8 billion annual research budget totaling. Of this sum, €1.5 billion is generated through contract research. More than 70 percent of the Fraunhofer-Gesellschaft’s contract research revenue is derived from contracts with industry and from publicly financed research projects. Almost 30 percent is contributed by the German federal and Länder governments in the form of base funding.
About Fraunhofer LBF (Division Smart Structures)
Smart 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. Smart Structures focuses specifically on vibration technology, light-weight design and functionality.
Main Contributions in IDEaliSM
In the ITEA project IDEaliSM a suitable method for the stiffness calculation of cable harness segments is developed. The method is implemented prototypically and interfaces to other tools in the process chain of the IDEaliSM project are considered. The output data can be used to parameterize laying simulations. The influence of clips, tapes and internal friction on the stiffness of cable harness segments is evaluated. Furthermore, the numerical simulation approach is validated with experimentally determined data. The preparation and test set-up is accompanied by Fraunhofer LBF; the measurements are performed by Dräxlmaier. For the simulation of the structural dynamics of flexible structures, a method for the integration of uncertainty analyses into a semi-automated simulation process is developed. The developed method can be transferred to tasks in automotive, aerospace and other engineering industries. Reduced time and computational costs for uncertainty analyses as well as reduced design time is expected. The main added value of Fraunhofer LBF is the experience and expertise in structural dynamics and vibration technology. Knowledge on the application of modern methods of numerical and experimental structural analysis is provided. Additionally, Fraunhofer LBF has experience in the field of modelling and simulation of the dynamic behaviour of single cables under consideration of geometric and material uncertainties as well as competences in the implementation of interfaces between engineering software tools and database management and (semi-) automation of software processes.
