Test Centre for Support Structures

11.11.2015

Manufacturers are offering ever larger and more powerful wind turbines for utilising wind power. Especially when these are installed offshore in the sea, extreme forces tug on the rotor blades, towers and foundations. The BINE-Projektinfo brochure “Testing towers and foundations” (05/2015) presents the Test Centre for Support Structures in Hanover. Here large-scale models and components are subjected to an advance time-lapse endurance test. The results will make it easier in future to design the supporting structures of wind turbines in accordance with needs.

The new centre has two large test rigs: the foundation test pit and the clamping field. In the 10-metre-deep pit filled with sand, large models of the support and foundation structures for offshore foundations can be mechanically loaded and investigated. Components and models are clamped in the clamping field.

Tensile, shear and torsional forces act on the object from different directions. The data obtained provides information on the extent and course of the material fatigue. In addition there is also a climate chamber and several specialist laboratories for conducting detailed analyses of concrete or the breakpoints of components that have failed during experiments.

Leibniz Universität Hannover operates the Hanover Test Centre for Support Structures together with the Fraunhofer Institute for Wind Energy and Energy System Technology, IWES, as its cooperation partner. In addition to this centre, the German Federal Ministry for Economic Affairs and Energy has spent a total of almost 50 million euros on further facilities for testing wind turbine nacelles and rotor blades as part of its energy research programme.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
