text: Eine Vielzahl von Prozessen in der Chemie und Verfahrenstechnik kann durch
Ultraschall positiv beeinflusst werden. Oftmals ist ultraschallinduzierte Kavitation
der Hauptwirkmechanismus für die positiven Effekte der Beschallung. Daher ist
es notwendig die Kavitationsaktivität während des Prozesses zu quantifizieren
um die Beschallung für den jeweiligen Prozess optimal gestalten und überwachen
zu können. Eine Möglichkeit der prozessbegleitenden Kavitationsdetektion ist die
Auswertung der akustischen Emissionen von oszillierenden und kollabierenden Kavitationsblasen
mittels Drucksensoren in der Flüssigkeit. Raue Prozessrandbedingungen wie hohe
Temperaturen oder aggressive Flüssigkeiten erschweren es jedoch geeignete Sensoren
zu finden. Als Alternative wurde daher die Nutzbarkeit der Rückwirkung von Kavitationsereignissen
auf das elektrische Eingansgssignal des Ultraschallwandlers zur Quantifizierung
von Kavitation untersucht. Die experimentelle Analyse hat ergeben, dass das Einsetzen
und in einigen Fällen auch die Art der Kavitation auf Basis der Rückwirkung auf
das Stromsignal des Ultraschallwandlers bestimmt werden kann. Die Stärke der Kavitation
war hingegen nicht aus den Stromsignalen abzuleiten.

text: Die starke Integration von Sensorik, Aktorik, Hard- und Software stellt Herausforderungen
an die Verlässlichkeit intelligenter mechatronischer Systeme dar. Diese Systeme
verfügen aber auch über großes Potential zur Verbesserung ihrer Verlässlichkeit
durch eine Anpassung des Systemverhaltens an den aktuellen Zustand. Um den Umfang
der Systemmodelle zu reduzieren und die Anpassung des Systemverhaltens zu ermöglichen,
sind fortschrittliche Modellierungsmethoden notwendig, mit denen die Verlässlichkeit
in frühen Phasen des Entwicklungsprozesses sichergestellt und evaluiert werden
kann. Von den Attributen der Verlässlichkeit ist insbesondere die Zuverlässigkeit
in hohem Maße von den auftretenden Belastungen an den Komponenten und damit vom
dynamischen Systemverhalten abhängig. Bisherige Modellierungsansätze bilden diese
Abhängigkeit nur unzureichend ab. Es wird daher ein Ansatz zur integrierten Modellierung
mechatronischer Systeme vorgestellt. Dieser ist in der Lage, sowohl die Dynamik
als auch die Zuverlässigkeit des Systems abzubilden. Die Transformation eines
Modells des dynamischen Systemverhaltens generiert dabei ein Zuverlässigkeitsmodell.
Für typischerweise konkurrierende Ziele können mit Hilfe von Mehrzieloptimierungsverfahren
Betriebspunkte eines Systems bestimmt werden. Das integrierte Modell kann zur
Erzeugung von Zielfunktionen für die Dynamik als auch für die Zuverlässigkeit
genutzt werden. Die Ergebnisse ermöglichen eine Verhaltensanpassung durch Wahl
eines paretooptimalen Betriebspunkts während des Betriebs. Das vorgeschlagene
Konzept zur integrierten Modellierung mechatronischer Systeme bietet aufgrund
des modellbasierten Entwicklungsansatzes und der automatisierten Transformation
eines Verlässlichkeitsmodells eine Reduktion der Benutzereingaben und eine Entlastung
des Benutzers. Dadurch wird die Wahrscheinlichkeit von Benutzerfehlern gesenkt
und die Verlässlichkeit bereits während der Entwicklung erhöht. Somit können Iterationsschleifen
vermieden und die Entwicklungskosten gesenkt werden.

text: Intelligent mechatronic systems are able to autonomously adapt system behavior
to current environmental conditions and to system states. To allow for such reactions,
complex sensor and actuator systems as well as sophisticated information processing
are required, making these systems increasingly complex. However, with the risk
of increased system complexity also comes the chance to adapt system behavior
based on current reliability and in turn to increase reliability. The adaptation
is based on switching selecting an appropriate working point at runtime. Multiple
suitable working points can be found using multi-objective optimization techniques,
which require an accurate system model including system reliability. At present,
modeling of system reliability is a laborious manual task performed by reliability
modelling experts. Despite actual system reliability being highly dependent on
system dynamics, pre-existing system dynamics models and the resulting reliability
model are at best loosely coupled. To allow for closer interaction among dynamics
and reliability model and to ensure these are always synchronized, advanced modeling
techniques are required. Therefore, an integrated model is introduced that reduces
user input to a minimum and that integrates system dynamics and system reliability.

text: This paper presents a comparison of a number of prognostic methods with regard
to algorithm complexity and performance based on prognostic metrics. This information
serves as a guide for selection and design of prognostic systems for real-time
condition monitoring of technical systems. The methods are evaluated on ability
to estimate the remaining useful life of rolling element bearing. Run-to failure
vibration and temperature data is used in the analysis. The sampled prognostic
methods include wear-temperature correlation method, health state estimation using
temperature measurement, a multi-model particle filter approach with model parameter
adaptation utilizing temperature measurements, prognostics through health state
estimation and mapping extracted features to the remaining useful life through
regression approach. Although the performance of the methods utilizing the vibration
measurements is much better than the methods using temperature measurements, the
methods using temperature measurements are quite promising in terms of reducing
the overall cost of the condition monitoring system as well as the computational
time. An ensemble of the presented methods through weighted average is also introduced.
The results show that the methods are able to estimate the remaining useful life
within error bounds of +-15\%, which can be further reduced to +-5\% with the
ensemble approach.

text: Intelligent mechatronic systems other the possibility to adapt system behavior
to current dependability. This can be used to assure reliability by controlling
system behavior to reach a pre-defined lifetime. By using such closed loop control,
the margin of error of useful lifetime of an individual system is lowered. It
is also possible to change the pre-defined lifetime during operation, by adapting
system behavior to derate component usage. When planning maintenance actions,
the remaining useful lifetime of each individual system has to be taken into account.
Usually, stochastic properties of a fleet of systems are analyzed to create maintenance
plans. Among these, the main factor is the probability of an individual system
to last until maintenance. If condition-based maintenance is used, this is updated
for each individual system using available information about its current state.
By lowering the margin of error of useful lifetime, which directly corresponds
to the time until maintenance, extended maintenance periods are made possible.
Also using reliability-adaptive operation, a reversal of degradation driven maintenance
planning is possible where a maintenance plan is setup not only according to system
properties, but mainly to requirements imposed by maintenance personnel or infrastructure.
Each system then adapts its behavior accordingly and fails according to the maintenance
plan, making better use of maintenance personnel and system capabilities at the
same time. In this contribution, the potential of maintenance plan driven system
behavior adaptation is shown. A model including adaptation process and maintenance
actions is simulated over full system lifetime to assess the advantages gained.

text: Intelligente technische Systeme, die in der Lage sind, sich an geänderte Umgebungsbedingungen
anzupassen, ermöglichen eine Adaption anhand der aktuell erreichten Zuverlässigkeit.
Zu diesem Zwecke kann ein geschlossener Regelkreis formuliert werden, der dazu
geeignet ist, den Betriebspunkt des Systems während der gesamten Lebensdauer anzupassen.
Dadurch wird eine harte Umschaltung während des Betriebs vermieden und die Verhaltensanpassung
ist vom Nutzer weitgehend unbemerkt möglich. Dazu wird die aktuelle Restlebensdauer
mit einer vorgegebenen Restlebensdauer verglichen. Durch Änderung der vorgegebenen
Restlebensdauer lässt sich auch eine Anpassung der gewünschten Nutzungsdauer erreichen,
beispielsweise um veränderte Wartungsintervalle einzuhalten. Zu diesem Zwecke
ist es allerdings notwendig, die aktuell erreichte Zuverlässigkeit zu schätzen.
Für die Regelung ist dabei die aktuelle Restlebensdauer der wichtigste Parameter,
da er als Istwert direkt mit der gewünschten Restlebensdauer als Sollwert verglichen
wird und als Reglereingang dient. Für die Genauigkeit der Regelung ist daher die
Bestimmung der Restlebensdauer von entscheidender Bedeutung. Es wird ein Modell
des Regelkreises vorgestellt, das auch den Einfluss einer fehlerhaften Restlebensdauerschätzung
auf die Verhaltensanpassung abbildet. Dadurch ist es möglich, Grenzen der Verhaltensanpassung
und die zur Einhaltung notwendige Genauigkeit der Restlebensdauerschätzung zu
bestimmen. Es gibt zahlreiche Ansätze, die Restlebensdauer zu schätzen, die aufgeteilt
werden in modellbasierte Verfahren und datengetriebene Verfahren. Die individuelle
Eignung eines jeden Verfahrens sowie die Modellbildung oder die Nutzung geeigneter
Algorithmen ist stark systemabhängig. Um die Auswahl von Verfahren und Modellen
oder Algorithmen zu ermöglichen, werden zunächst die Anforderungen an die Restlebensdauerschätzung
zur Nutzung als Regelungs-Istwert bestimmt. Verschiedene Verfahren werden sodann
hinsichtlich ihrer Eignung evaluiert und Anwendungsgrenzen aufgezeigt.

text: Ultrasonic wire bonding is an indispensable process in the manufacturing of
semiconductor components. It is used for interconnecting the silicon die to e.g.
connectors in the housing or to other semiconductors in complex components. In
high power applications, such as wind turbines, locomotives or electric vehicles,
the thermal and mechanical limits of interconnects made from aluminum are nearing.
The limits could be overcome using copper wire bonds, but their manufacturing
poses challenges due to the harder material, which leads to increased wear of
the bond tools and to less reliable production. To overcome these drawbacks, adaptation
of process parameters at runtime is employed. However, the range of parameter
values for which a stable process can be maintained is very small, making it necessary
to compute suitable parameters beforehand. To this end, and to gain insights into
the process itself, the ultrasonic bonding process is modeled. The full model
is composed of several partial models, some of which were introduced before. This
paper focuses on the modularization of the full model and on the interaction of
partial models. All partial models are presented, their interaction is shown and
the general outline of the simulation process is given.

text: The contact between viscoelastic materials e.g. elastomers and a rough surface
leads to a special friction characteristic, which differs greatly in its properties
comparing to other materials like metals. In practice, this friction combination
occurs for example in the tire-road contact, or in the use of rubber gaskets.
Due to the frictional forces a system is significantly influenced in its vibrational
properties. The friction force is composed of two main components adhesion and
hysteresis. The adhesion results from molecular bounds between the contact partners,
while the deformation of the viscoelastic material by the roughness of the counter
body leads to power loss. This internal friction results in an additional frictional
force, which is described by the hysteresis. To simulate the frictional behaviour
of elastomers on rough surfaces and thus to determine the energy dissipation in
contact, it is necessary to develop a mechanical model which considers the roughness
of the contact partners, as well as dynamic effects and the dependence on normal
pressure and sliding speed. The viscoelastic material behaviour must also be considered.
The contact between two rough surfaces is modelled as a rough rigid layer contacting
a rough elas- tic layer. The elastic layer is modelled by point masses connected
by Maxwell-elements. This allows the viscoelastic properties of the elastomer
to be considered. The behaviour of whole system can be described by equations
of motion with integrated constraints. The degrees of freedom of the model depends
on the varying contact conditions. A point mass not in contact has two degrees
of freedom. A point mass in contact moving along the roughness path can be described
by only one degree of freedom. For each Maxwell-Element also an inner coordinate
and thus a further degree of freedom is needed. Because of varying contact conditions
dur- ing the simulation, the simulation interrupts in case the contact conditions
change. Then the equations of motions are adapted with respect to the contact
constraints. As a result of the simulation one obtain the energy dissipation and
thus the friction char- acteristic during the friction process. It is possible
to use these results in three dimensional point-contact elements in order to model
contact surfaces on lager length scales.

text: To increase quality and reliability of copper wire bonds, self-optimization
is a promising technique. For the implementation of self-optimization for ultrasonic
heavy copper wire bonding machines, a model of stick-slip motion between tool
and wire and between wire and substrate during the bonding process is essential.
Investigations confirm that both of these contacts do indeed show stick-slip movement
in each period oscillation. In a first step, this paper shows the importance of
modeling the stick-slip effect by determining, monitoring and analyzing amplitudes
and phase angles of tool tip, wire and substrate experimentally during bonding
via laser measurements. In a second step, the paper presents a dynamic model which
has been parameterized using an iterative numerical parameter identification method.
This model includes Archard's wear approach in order to compute the lost volume
of tool tip due to wear over the entire process time. A validation of the model
by comparing measured and calculated amplitudes of tool tip and wire reveals high
model quality. Then it is then possible to calculate the lifetime of the tool
for different process parameters, i.e. values of normal force and ultrasonic voltage.
