@article{33523, abstract = {{Die thermisch verursachte, plastische Verformung an statischen Druckplatten von Lamellenbremsen kann das Betriebsverhalten von Bremsen nachhaltig stören und sollte daher vermieden werden. So kann die plastische Verformung der Druckplatte beispielsweise zu einer Verkleinerung des Luftspalts führen und ungewollte Veränderung der Reibverhältnisse verursachen. Während des Bremsvorgangs dehnen sich hoch erwärmte Bereiche nah der Reibfläche aus und werden von den Zonen geringerer Temperatur an ihrer Ausdehnung gehindert. Überschreiten die daraus resultierenden Spannungen die Dehngrenze des Materials, kommt es zu plastischer Verformung. Dieser Artikel erläutert den physikalischen Verformungsprozess detailliert und darauf aufbauend, welche Maßnahmen zu einer Verringerung der Verformung ergriffen werden können. Dazu werden im Rahmen theoretischer Vorüberlegungen drei Ansätze identifiziert, die sowohl die Geometrie als auch die Werkstoffe der Druckplatten betreffen. Radiale Schlitze sollen die Behinderung der thermischen Dehnung verhindern und dadurch Spannungen reduzieren; die Werkstoffauswahl auf Basis der Thermoschockempfindlichkeit reduziert die plastische Verformung. Anhand einer kombinierten Simulation der Thermik und der Mechanik einer Druckplatte wird der Effekt dieser Ansätze an vier Varianten der Druckplatte überprüft. Experimentelle Untersuchungen an realen Prototypen der Druckplattenvarianten bestätigen die Ergebnisse der Simulation und weisen die Wirksamkeit der vorgeschlagenen Maßnahmen zur Reduzierung der plastischen Verformung nach.}}, author = {{Schadomsky, Magnus and Blumenthal, Lars Martin and Zimmer, Detmar and Peter, Simon and Boros, Laszlo}}, issn = {{0015-7899}}, journal = {{Forschung im Ingenieurwesen}}, keywords = {{General Engineering, Bremsen, Bremsscheiben, thermoplastische Verformung}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Maßnahmen zur Reduzierung von plastischer Verformung an statischen Druckplatten von Lammellenbremsen infolge einseitig eingebrachter hoher Reibleistung}}}, doi = {{10.1007/s10010-022-00601-2}}, year = {{2022}}, } @phdthesis{33499, author = {{Otroshi, Mortaza}}, isbn = {{978-3-8440-8777-2}}, issn = {{1434-6915}}, pages = {{128}}, publisher = {{Shaker Verlag}}, title = {{{Damage modeling in the numerical simulation of mechanical joining processes}}}, doi = {{https://doi.org/10.2370/9783844087772}}, year = {{2022}}, } @inproceedings{30123, author = {{Otroshi, Mortaza and Meschut, Gerson}}, location = {{Pittsburg, Pennsylvania, USA}}, title = {{{Investigation of the three-dimensional stress state during loading of self-piercing riveted joints}}}, year = {{2022}}, } @inproceedings{33561, author = {{Tews, Karina and Teutenberg, Dominik and Meschut, Gerson}}, location = {{Blankenburg (Harz)}}, title = {{{Experimentelle Untersuchung des Ermüdungsverhaltens und Berechnung der Lebensdauer von Stahlklebverbindungen bei multiaxialer Belastung}}}, year = {{2022}}, } @inbook{33728, author = {{Bielak, C.

As a fixing method for hybrid joining with structural adhesive, clinching has the advantage over other mechanical joining technologies that different materials can be joined without an auxiliary joining part and pre-hole. Due to the large degree of deformation in the joining partners, strong in-plane and out-of-plane material flows occur during the setting process, which can lead to plastic deformation. The aim of this work is the further development of shear-clinching for low-deformation of aluminium-steel joints. To gain a basic understanding of the joint deformation, the deformation of the joint partners during the setting process is identified step by step. Based on the knowledge gained, the deformation-related influencing factors are investigated experimentally. Thus, optimisation approaches as well as suggested handling methods for the production of a low-deformation shear-clinching joint are derived. For the realisation of the common narrow flange, which is to be characterised as deformation-sensitive due to a small edge distance, a numerically supported tool modification is carried out and subsequently experimentally validated. }}, author = {{Han, Daxin}}, title = {{{Deformationsarme Fügeverbindungen mittels prozessoptimiertem Schneidclinchen}}}, year = {{2022}}, } @inproceedings{33914, abstract = {{Workshops on business model generation lead to collaborative work phases and discussions on business models.
