The last stage of many manufacturing processes used in polymer processing industry are primary forming processes such as extrusion or injection molding. If melts of semicrystalline plastics are subjected to such processes, temperature control opens up the possibility of influencing solid state properties. This concerns those that depend on crystallinity, as it is possible to enhance crystallization by slow cooling or to suppress it by quenching. However, during the forming process the melt rarely rests, so that solidification processes in flows occur. Those complex processes can only be...

Das hochautomatisierte Fahren im Hub-to-Hub-Anwendungsfall bietet erhebliches Potenzial, den Fahrermangel im Lkw-Bereich zu entschärfen und Lkw-bedingte Unfälle zu verringern. Die Sicherheit solcher Systeme muss durch szenariobasiertes Testen in Simulationsumgebungen gewährleistet werden, da reale Tests aufgrund wirtschaftlicher und sicherheitstechnischer Bedenken oft unpraktikabel sind. Die Genauigkeit des Fahrzeugmodells, das Fahrbefehle in kinematische Zustande umwandelt, ist in diesen Simulationen entscheidend, da Ungenauigkeiten die Bewertung des Automatisierten Fahrsystems (ADS)...

In the automotive industry, the suppression of unwanted noise, such as brakenoise, plays an important role within the manufacturing process of vehicles.These noises decrease the perceived quality and should therefore be detected andeliminated early on in the development process. In addition to measurementson real assemblies, simulation-based prediction of brake noise is also used. Inindustrial applications, the (linear) Complex Eigenvalue Analysis (CEA) of themathematical brake models is commonly used as simulation-based detection. TheCEA detects e.g. creep groan vibrations at an unstable...
