Collaborative Research Centres

In order to manage future wind farms, precise information about the condition and dynamic behaviour of the support structure and the rotor blades must be collected over the entire working life of each turbine, as well as information regarding the effects of changing environmental or operating conditions. With the concept of a digital twin, the Collaborative Research Center is developing a method that integrates all these details. Compared to current models, such wind turbines could generate electricity more efficiently, while providing a more continuous supply of electricity. In terms of output, they could be installed in a more time-efficient manner while reducing maintenance costs.

In the Transregio - SFB "SIIRI", more than 150 scientists from the Hannover Medical School (MHH), Leibniz Universität Hannover, of the Helmholtz Centre for Infection Research in Braunschweig, the Technical University of Braunschweig and the University of Music, Drama and Media (HMTMH) jointly research the development of new implants to increase patient safety. Since 2021, researchers from a wide range of disciplines work together to develop intelligent implant systems for dentistry and orthopaedics as well as hearing implants, which for the first time will use the latest technology to allow continuous monitoring of implant function and thereby early detection of complications such as infections.

Participating Institute of the Faculty of Civil Engineering and Geodetic Science:

• Institute of Mechanics and Computational Mechanics (IBNM): Surrogate-modelling for monitoring of implants (A07)

The Collaborative Research Centre TerraQ (2021 - 2025) brought together a unique combination of physicists, geodesists, sensor developers, and users in geodetic fields, complemented by engineers and fundamental researchers. The results from TerraQ research, such as the geodetic use of transportable optical clocks, prototypes of chip-based atom interferometers, and advancements in laser interferometry in space, now serve as a robust foundation for future high-level research and applications in gravimetric Earth observation. The research will continue as part of other collaborative research projects. For example, in the QuantumFrontiers Cluster of Excellence or the DQ-mat Collaborative Research Centre.

From 2010 to 2022, the Collaborative Research Center (CRC) 871 "Regeneration of Complex Capital Goods" contributed to developing a scientific basis for maintaining complex capital goods. In addition to twelve institutes from three faculties of the Gottfried Wilhelm Leibniz University Hannover, the Laser Zentrum Hannover and an institute of the Technical University Braunschweig were participating in the Collaborative Research Centre 871.

Participating Institutes of the Faculty of Civil Engineering and Geodetic Science:

• Institute for Risk and Reliability: Subproject D5 Resilience Based Decision Criteria for Optimal Regeneration
• Institute of Structural Analysis: Subproject B4 Stochastic Structural Analysis
