C.- Krise und die Digitalisierung der Hochschulen

Der wissenschaftliche Beirat des BmWE kritisiert hier im Dossier die Folgen der schleppenden Digitalisierung, die in der Krise die bisherigen Defizite in der öff. Verwaltung, konkret in den Hochschulen gezeigt haben:  “Es wird weiterer Maßnahmen bedürfen, um die digitale Transformation der deutschen Hochschulen an internationale Standards heranzuführen.” (S.10)
“Zu den in Frage kommenden Handlungsoptionen gehört zunächst die Förderung der Forschung und Entwicklung, insbesondere in Bereichen, die für die Digitalisierung relevant sind. In mittelständischen Unternehmen zeigen sich zudem, wie bei früheren technologischen Veränderungen, Informationsdefizite, die durch eine niederschwellige Förderung von Beratungsleistungen (Digital-Voucher) zumindest teilweise behoben werden können. Beispiele für solche Fördermaßnahmen gibt es bereits mit den Programmen „go-digital“, „go-inno“ und „Digital Jetzt“, die aber nur eine kleine Zahl von KMU erreichen” (S.19)

Das macht mir Mut, das von außen anzupacken!

Vergleich aktuelle Investitionen Forschung und Entwicklung

Dr. Holger Schmidt
„Europas digitale Forschungslücke
Die Ausgaben für Forschung und Entwicklung sind in den vergangenen 20 Jahren gestiegen, allerdings in Ländern wie den USA, Südkorea, Taiwan, Israel oder China wesentlich stärker als in der EU. Wesentlicher Grund ist die Digitalisierung, in die der Großteil dieser zusätzlichen Forschungsausgaben geflossen ist. Während Israel oder Südkorea inzwischen rund 5 Prozent ihres BIP in die Forschung investieren, liegt der Wert in Europa kaum verändert bei zwei Prozent. Pro Kopf der Bevölkerung (gerechnet in Kaufkraftparitäten) geben die USA, Israel, Südkorea und Taiwan inzwischen 2000 PPP-Dollar pro Jahr für Forschung und Entwicklung aus. In Europa liegt der Wert nur halb so hoch, zeigen neue OECD-Zahlen.“

Recycling construction Recyclable material

“Germany has a problem with end-of-life vehicle disposal. Only every fifth car that is ready for scrap is actually professionally dismantled and disposed of in this country. This means that 80 percent of cars disappear from the gray market and are exported, for example, to countries where there is no legally prescribed recycling. The recycling industry and thus the automotive industry are losing vast amounts of raw materials. This not only harms the local economy, but also the global protection of resources. Ultimately, primary raw materials have to be purchased at high prices for the production of new vehicles, and their degradation also has a negative impact on the climate and the environment. So there are good reasons not to simply take the current situation in terms of end-of-life vehicle recycling as a given, but to actively work out solution concepts. TSR has taken on this task and, together with Scholz Recycling GmbH, launched the research project used car recycling or commissioned a study on this.

One task of the study was to analyze car bodies with regard to their components. And that in perspective – in other words, with a view to the vehicles that are built today and will then be recycled in ten or more years. Among other things, it emerged that the material composition of scrap cars will change significantly by 2030. Models that were recycled in 2000 were still made of more than 70 percent steel. For end-of-life vehicles by 2030, the value drops to only around 55 percent. In return, the proportion of over 50 different plastics and plastic composites increases from 15 to almost 30 percent. So there are major challenges in the recycling of junk bodies. This will make it even more difficult to comply with statutory recycling quotas.”

Hybrid spindle: Process-dependent setting of the spindle dynamics to increase productivity in machining

Various storage concepts for the hybrid spindle were initially developed and implemented in
Examined within the framework of numerical simulations with regard to the thermo-elastic behavior. The storage temperatures and thermal
Induced bearing deformations are used to design the preload element. The prestressing force is applied by the prestressing element via spring forces. A deformation of the spindle bearings leads to a change in the deflection and thus to a change in the preload force. The
adaptive prestressing element is therefore designed so that the change in prestressing force as a result
thermally induced deformations can be compensated. In cooperation with representatives from the industry, a practical maximum nominal speed of
n = 20,000 rpm and a rated motor power Pn = 60 kW. Based on the performance and

The resulting hybrid spindle was then put into a machine tool of the type NN PFV-1 integrated and experimentally investigated at the IFW. The experimental investigations include the implementation of modal analyzes and machining tests.
The steps involved in designing and testing the hybrid spindle are described in more detail below
