text: We present a data acquisition and visualization pipeline that allows experts
to monitor additive manufacturing processes, in particular laser metal deposition
with wire (LMD-w) processes, in immersive virtual reality. 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. Therefore, it serves as a first promising step
towards the successful application of virtual reality technology in the comparatively
young field of additive manufacturing.

text: AbstractEngineering projects for complex
technical systems such as automobiles demand extensive requirement specifications
and corresponding hierarchy levels in system architectures. 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.
The concept proved to be indispensable and transferable to other Systems Engineering
projects.

text: AbstractPolycarbonate (PC) is an amorphous
polymer that is an extremely robust material with a high tenacity, and thus suitable
for a lightweight construction with glass‐like transparency. 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. In future work, the displacement fields and the resulting reaction
forces will be used for parameter identification of constitutive equations.

text: AbstractCold forming of polycarbonate films
results in the formation of shear bands in the necking zone. 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.

text: AbstractA new control method aims at the
precise high dynamic control of the force signal for experimental vibration analysis,
which is generated by an electrodynamic shaker. 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.

text: The widespread adoption of ultra-high strength steels, due to their high bulk
resistivity, intensifies expulsion issues in resistance spot welding (RSW), deteriorating
both the spot weld and surface quality. 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.

text: Die vorliegende Dissertation beschreibt das Konzept und den Entwicklungsprozess
eines Lichtsignalanlagenregelungssystems bis zur Realumsetzung. Das Regelungssystem,
welches im Rahmen des Pilotprojekts Schlosskreuzung entstanden ist, besteht dabei
aus zwei untereinander abgestimmten Methoden zur Echtzeit-Verkehrsrekonstruktion
und zur modellprädiktiven Regelung des Verkehrssystems anhand der vorhandenen
Lichtsignalanlagen. Die Echtzeit-Verkehrsrekonstruktion approximiert dabei simulationsbasiert
den aktuellen Verkehrszustand anhand gegebener Messdaten über dynamische Verkehrszuweisungen.
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. Entsprechende Ergebnisse
zeigen das große Potential der Entwicklung hinsichtlich der Reduktion von Kriterien
wie Emissionen oder Wartezeiten und gleichzeitig den Handlungsbedarf für eine
standardmäßige Nutzung.

text: This dissertation describes the concept and the development process of a traffic
signal control system up to the real implementation.The control system, which
was developed in the context of the Pilotprojekt Schlosskreuzung, consists of
two mutually coordinated methods for real-time traffic reconstruction and for
model-predictive control of the traffic system based on the existing traffic light
systems.The real-time traffic reconstruction approximates the current traffic
state simulation-based using given measurement data via dynamic traffic assignments.The
designed multi-stage traffic signal control system uses a fuzzy-system for phase
preselection and subsequently employs model predictive control to solve the nonlinear
problem resulting in the optimal combinations of phases and switching times.In
this work, the control system is first tested purely simulatively on the basis
of a selected traffic area and compared with the existing inventory method.Following
the prototypical commissioning, this comparison is finalised by field tests.Corresponding
results show the great potential of the development with regard to the reduction
of criteria such as emissions or waiting times and at the same time the need for
action for use as standard.

text: "Ziel dieser Arbeit ist die Entwicklung eines modellbasierten Beobachters
für eingangsaffine, nichtlineare Systeme, der trotz Modellungenauigkeiten eine
hohe Schätzgüte erzielt und zusätzlich eine parametrische, physikalisch interpretierbare
Darstellung dieser ermöglicht. 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. "

text: "The aim of this thesis is the development of a model-based observer for input-affine,
nonlinear systems that achieves a high estimation quality despite model inaccuracies.
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
