Our virtual environment consists of a digital shadow of the LMD-w production site enriched with additional measurement data shown on both static as well as handheld virtual displays. Users can explore the production site by enhanced teleportation capabilities that enable them to change their scale as well as their elevation above the ground plane. In an exploratory user study with 22 participants, we demonstrate that our system is generally suitable for the supervision of LMD-w processes while generating low task load and cybersickness.

Especially when considering emergent phenomena, such as total weight or aerodynamics, a closely networked collaboration of discipline‐specific and cross‐disciplinary roles is required. Further, in large organizations with a group structure, resulting functional and non‐functional contents need to be managed by distinct Systems Engineering roles. For example, the role “property manager” takes care of achieving overarching product properties, such as weight or aerodynamics, which cannot be directly fixed, but result from many specifications. This paper proposes new Systems Engineering roles and their application in a German Original Equipment Manufacturer (OEM). For validation, the roles have already been applied in everyday engineering projects at the OEM.

Due to these advantageous properties, PC is often used in industry for example in medical devices, automotive headlamps, sporting equipment, electronics, and a variety of other products. PC is often subjected to uniaxial and biaxial loading conditions. Therefore, reliable material models have to take into account the various resulting experimental effects. For those reasons, we investigate PC specimens under uniaxial and biaxial loading by using different stretch rates and loading scenarios. In addition to that, we propose methods for optical measurement of local stretches to obtain the approximated local true stress.

The numerical results obtained from standard viscoplastic material models exhibit mesh size dependency, requiring mathematical regularization. For this purpose, we present in this work a large deformation gradient theory for a viscoplastic isotropic material model published before. We extend our model to a micromorphic model by introducing a new micromorphic variable as an additional degree of freedom along with its first gradient. This variable represents a microequivalent plastic strain. The relation between the macroequivalent plastic strain and the micromorphic variable is accomplished by a micromorphic coupling modulus. This coupling forces proximity between the macro- and microvariables, leading to the targeted regularization effect. The micromorphic model is implemented as a three-dimensional initial boundary value problem in an in-house finite element tool. The analysis is performed for both uniaxial and biaxial specimens. The provided numerical examples show the ability of our model to regularize shear bands within the specimens and address the issue of localization.</jats:p>"}],"language":[{"iso":"eng"}],"doi":"10.1007/s00419-024-02570-0","publication_identifier":{"issn":["0939-1533","1432-0681"]},"author":[{"id":"57708","full_name":"Hamdoun, Ayoub","first_name":"Ayoub","last_name":"Hamdoun"},{"full_name":"Mahnken, Rolf","first_name":"Rolf","last_name":"Mahnken","id":"335"}],"title":"A large deformation gradient theory for glassy polymers by means of micromorphic regularization","year":"2024","intvolume":"        94","publication_status":"published","date_updated":"2024-09-26T11:25:44Z","citation":{"mla":"Hamdoun, Ayoub, and Rolf Mahnken. “A Large Deformation Gradient Theory for Glassy Polymers by Means of Micromorphic Regularization.” <i>Archive of Applied Mechanics</i>, vol. 94, no. 5, Springer Science and Business Media LLC, 2024, pp. 1221–42, doi:<a href=\"https://doi.org/10.1007/s00419-024-02570-0\">10.1007/s00419-024-02570-0</a>.","ama":"Hamdoun A, Mahnken R.

A bending beam is used as a nonlinear test object. A design and a surrogate model of the test rig are shown and parameterized based on test rig measurements. The force control algorithm using input/output linearisation is described and implemented in Matlab/Simulink for simulative validation studies. Conclusions drawn from the mathematical description of the problem as well as simulation results show that the design of the contact between shaker and test object is crucial to achieve a high control bandwidth and at the same time reduce the energy consumption of the shaker. This leads to the practical application using a novel damping contact element. Finally, experimental test rig results are presented which show a closed loop bandwidth of at least 250 Hz for sinusoidal excitation signals.</jats:p>"}],"date_created":"2024-10-14T08:11:05Z","department":[{"_id":"153"}],"type":"journal_article","status":"public","_id":"56608","publisher":"Springer Science and Business Media LLC","volume":88,"user_id":"22675","citation":{"bibtex":"@article{Lüke_Trächtler_2024, title={Highly dynamic force control for experimental vibration analysis with an electrodynamic shaker Hochdynamische Kraftregelung für die experimentelle Schwingungsanalyse mit einem elektrodynamischen Shaker}, volume={88}, DOI={<a href=\"https://doi.org/10.1007/s10010-024-00757-z\">10.1007/s10010-024-00757-z</a>}, number={139}, journal={Forschung im Ingenieurwesen}, publisher={Springer Science and Business Media LLC}, author={Lüke, Christopher and Trächtler, Ansgar}, year={2024} }","ama":"Lüke C, Trächtler A.

This study presents a novel approach to prevent expulsion by employing a preheating current. Through characteristic analysis of joint formation under critical welding current, the importance of plastic material encapsulation around the weld nugget (plastic shell) at high temperatures in preventing expulsion is highlighted. To evaluate the effect of preheating on the plastic shell and understand its mechanism in expulsion prevention, a two-dimensional welding simulation model for dissimilar ultra-high strength steel joints was established. The results showed that optimal preheating enhances the thickness of the plastic shell, improving its ability to encapsulate the weld nugget during the primary welding phase, thereby diminishing expulsion risks. Experimental validation confirmed that by employing the optimal preheating current, the maximum nugget diameter was enhanced to 9.42 mm, marking an increase of 13.4 % and extending the weldable current range by 27.5 %. Under quasi-static cross-tensile loading, joints with preheating demonstrated a 7.9 % enhancement in maximum load-bearing capacity compared to joints without preheating, showing a reproducible and complete pull-out failure mode within the heat-affected zone. This study offers a prevention method based on underlying mechanisms, providing a new perspective for future research on welding parameter optimization with the aim of expulsion prevention."}],"publication":"Journal of Manufacturing Processes","department":[{"_id":"157"}],"type":"journal_article","keyword":["Expulsion Resistance spot welding Finite element modelling Preheating Weldable current range Ultra-high strength steel"],"date_created":"2024-06-23T21:58:29Z","file":[{"creator":"kekeyang","date_created":"2024-06-23T21:59:20Z","date_updated":"2024-06-23T21:59:20Z","relation":"main_file","file_size":12432409,"access_level":"closed","file_name":"1-s2.0-S1526612524006145-main.pdf","success":1,"content_type":"application/pdf","file_id":"54848"}],"intvolume":"       124","article_type":"original","date_updated":"2024-10-18T06:59:27Z","publication_status":"published","publication_identifier":{"issn":["1526-6125"]},"author":[{"id":"65085","full_name":"Yang, Keke","last_name":"Yang","orcid":"0000-0001-9201-9304","first_name":"Keke"},{"first_name":"Bassel","last_name":"El-Sari","full_name":"El-Sari, Bassel"},{"last_name":"Olfert","first_name":"Viktoria","full_name":"Olfert, Viktoria","id":"5974"},{"last_name":"Wang","first_name":"Zhuoqun","full_name":"Wang, Zhuoqun"},{"full_name":"Biegler, Max","last_name":"Biegler","first_name":"Max"},{"first_name":"Michael","last_name":"Rethmeier","full_name":"Rethmeier, Michael"},{"id":"32056","full_name":"Meschut, Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","first_name":"Gerson"}],"title":"Expulsion prevention in resistance spot welding of dissimilar joints with ultra-high strength steel: An analysis of the mechanism and effect of preheating current","year":"2024","doi":"10.1016/j.jmapro.2024.06.034","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S1526612524006145","open_access":"1"}]},{"date_created":"2024-10-18T07:59:48Z","department":[{"_id":"43"},{"_id":"157"}],"type":"conference","citation":{"ama":"Einwag J-M, Goetz S, Wartzack S.

Die entwickelte mehrstufige Lichtsignalanlagenregelung nutzt ein Fuzzy-System zur Phasenvorauswahl, um anschließend über eine modellprädiktive Regelung das nichtlineare Problem mit dem Ergebnis der optimalen Kombinationen von Phasen und Schaltzeitpunkten zu lösen. Das Regelungssystem wird in dieser Arbeit anhand eines ausgewählten Verkehrsgebiets zunächst rein simulativ getestet und mit dem vorliegenden Bestandsverfahren verglichen. Im Anschluss an die prototypische Inbetriebnahme wird dieser Vergleich durch die Feldtests abgeschlossen.

Diese soll zur automatisierten Verbesserung des Modells verwendet werden. Die vorliegende Arbeit analysiert sowohl Techniken der hybriden Systemidentifikation wie physikalisch motivierte neuronale Netze, als auch Methoden zur Kompensation von Modellungenauigkeiten im Beobachterentwurf. Basierend auf der Analyse wird ein neuartiger, modellbasierter Beobachter entworfen, der Systemzustände und Modellungenauigkeiten gleichzeitig schätzt und insbesondere eine parametrische, physikalisch interpretierbare Darstellung der Ungenauigkeiten erzielt. Diese besteht aus einer Linearkombination von physikalisch interpretierbaren Funktionen, deren dazugehörige, dünnbesetzt modellierte Parameter mithilfe eines augmentierten Zustands parallel zu den Systemzuständen geschätzt werden. Das Novum dieser Arbeit stellt somit die echtzeitfähige Schätzung von Zuständen und Modellungenauigkeiten in physikalisch-technischer Form dar, auf deren Grundlage ein Konzept zur automatisierten Modelladaption umgesetzt wird. Die Applikation der neuartigen Methode ist in der Situation auftretender Systemveränderungen besonders vorteilhaft, da diese zur Laufzeit durch den augmentierten Beobachter\r\ngeschätzt und identifiziert werden können.

By additionally providing a parametric, physically interpretable representation of the model inaccuracies, an automated improvement of the model should be enabled. This thesis\r\nanalyzes techniques of hybrid system identification such as physics-guided neural networks, as well as methods for compensating model inaccuracies within the observer design. Based on this analysis, a novel model-based observer is designed, which estimates states and model inaccuracies jointly and, in particular, obtains a parametric, physically\r\ninterpretable representation of the inaccuracies. This consists of a linear combination of physically interpretable functions, whose associated parameters are modeled sparse and estimated in parallel to the system’s states using an augmented state. The novelty of this thesis is thus the real-time capability to jointly estimate states and model inaccuracies in a physical-technical manner, on the basis of which an automated model adaption can be\r\ncarried out. The application of the new methodology is particularly advantageous in the situation of occurring system changes since these can be estimated and identified at run time by the augmented observer.","lang":"eng"}],"series_title":"Verlagsschriftenreihe des Heinz Nixdorf Instituts","language":[{"iso":"ger"}],"doi":"10.17619/UNIPB/1-2066","title":"Online-Schätzung von Modellungenauigkeiten zur automatischen Modelladaption unter Beibehaltung einer physikalisch-technischen Interpretierbarkeit","year":"2024","author":[{"full_name":"Götte, Ricarda-Samantha","first_name":"Ricarda-Samantha","last_name":"Götte","id":"43992"}],"publication_identifier":{"isbn":["978-3-947647-42-2"]},"date_updated":"2024-11-07T11:47:59Z","publication_status":"published","intvolume":"       423","supervisor":[{"first_name":"Julia","last_name":"Timmermann","full_name":"Timmermann, Julia","id":"15402"},{"full_name":"Mikut, Ralf","last_name":"Mikut","first_name":"Ralf"}],"citation":{"chicago":"Götte, Ricarda-Samantha. <i>Online-Schätzung von Modellungenauigkeiten zur automatischen Modelladaption unter Beibehaltung einer physikalisch-technischen Interpretierbarkeit</i>.
