Thanks to a new software program, components that only exist in the form of CAD data can be virtually installed in the new car model by the assembly planners. If a component is too large to be maneuvered into place, the program gives concrete advice on where to change its shape.
The software was developed and has now been further improved by researchers at the Fraunhofer-Chalmers Research Centre for Industrial Mathematics FCC in Gothenburg, Sweden, and the Fraunhofer Institute for Industrial Mathematics ITWM in Kaiserslautern. "We can also include the pliability of components in the assembly simulation," says ITWM group manager Dr.-Ing. Joachim Linn.
"In the CAD data, flexible components such as plastic parts for the passenger compartment appear rigid, but during assembly they have to be slightly bent and pressed." How much force needs to be applied to bend the dashboard far enough to install it in the car?
Can the job be done by just one employee and are special tools required? How can flexible brake hoses be installed most efficiently? The researchers also simulate the use of assembly robots, whose flexible supply lines often scrape against the car body, leaving small scratches. The program computes how the robot should move and fit the parts so that the cables do not hit the bodywork.
These computations are fast – like the CAD programs the designers are used to. "You can work interactively with the program, for example to make a component longer or shorter in just a few seconds. For this purpose we slimmed down the highly accurate structure-mechanical computation processes.
The results are still accurate enough but are delivered in real time," says Linn. Assembly paths, too, are computed within minutes. The researchers will give a live demonstration of the program at the Hannover-Messe (Hall 17, Stand D60) from April 20 to 24. The software is due to be launched on the market before the end of the year; support services and training material are already available.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
