  text: Additive Manufacturing offers a high potential in the aerospace due to its
    freedom of design and the ability to manufacture complex and lightweight parts.
    Profound changings of the existing processes can be expected for the area of Maintenance,
    Repair and Overhaul (MRO) as well. It is described with the help of scenarios
    which chances result from the integration of this technology while different applications
    are considered. It starts with the implementation of AM as another manufacturing
    technology for the repair of spare parts. The precision reduces the effort for
    post-processing in comparison to the conventional manufacturing methods such as
    the build-up welding. If an unexpected part breakdown occurs and the aircraft
    has to stay on ground, there are high demands on the logistics to deliver the
    required spare parts from the warehouse as fast as possible. The storage of spare
    parts causes extremely high costs and can be considerably reduced with the help
    of Additive Manufacturing. Distributed generative manufacturing centers can lead
    to a far-reaching restructuring of the existing processes where the required spare
    part is manufactured locally on demand. The resulting opportunities and risks
    for the involved market actors are shown within the presentation. It is described
    how MRO service providers and OEMs are affected by that and which changes of today’s
    processes are necessary to implement the presented scenarios.

  text: Fused Deposition Modeling (FDM) parts are prone to process-related rough and
    wavy surfaces with stair-stepping effects whenever the parts produced have sloped
    or rounded geometries. These stair-stepping effects can be reduced by using a
    smaller slice height, but complete elimination is not possible. In this paper,
    FDM parts manufactured with the material ABS-M30 are finished using mass finishing
    methods. The mass finishing is done with a trough vibrator, which is comparatively
    gentle to the parts in comparison to other mass finishing technologies. The analysis
    discusses the surface-smoothing effect of finishing time and intensity on various
    part sizes and build orientations. In addition, the dimensional accuracy of the
    parts after the finishing process is examined.

  text: In order to increase mechanical strength, heat dissipation and ampacity and
    to decrease failure through fatigue fracture, wedge copper wire bonding is being
    introduced as a standard interconnection method for mass production. To achieve
    the same process stability when using copper wire instead of aluminum wire a profound
    understanding of the bonding process is needed. Due to the higher hardness of
    copper compared to aluminum wire it is more difficult to approach the surfaces
    of wire and substrate to a level where van der Waals forces are able to arise
    between atoms. Also, enough friction energy referred to the total contact area
    has to be generated to activate the surfaces. Therefore, a friction model is used
    to simulate the joining process. This model calculates the resulting energy of
    partial areas in the contact surface and provides information about the adhesion
    process of each area. The focus here is on the arising of micro joints in the
    contact area depending on the location in the contact and time. To validate the
    model, different touchdown forces are used to vary the initial contact areas of
    wire and substrate. Additionally, a piezoelectric tri-axial force sensor is built
    up to identify the known phases of pre-deforming, cleaning, adhering and diffusing
    for the real bonding process to map with the model. Test substrates as DBC and
    copper plate are used to show the different formations of a wedge bond connection
    due to hardness and reaction propensity. The experiments were done by using 500
    $\mu$m copper wire and a standard V-groove tool.

  text: Cavitation monitoring is desired to optimize the sonication for diverse sonochemical
    processes and to detect changes or malfunctions during operation. In situ cavitation
    measurements can be carried out by detection of the acoustic emissions of cavitation
    bubbles by sensors in the liquid. However, in harsh environments sensors might
    not be applicable. Thus, the impact of cavitation on the electrical signals of
    a piezoelectric transducer has been analyzed as alternative method to measure
    the threshold, strength and type of cavitation. The applicability has been tested
    in three different setups to evaluate the general- izability of extracted indicators.
    In all setups indicators for the cavitation thresholds could be derived from the
    current signal. In two setups features showed two thresholds that may be linked
    to the types of cavitation. However, only one feature derived from the current
    signal in one particular setup correlated to the strength of cavitation. Cavitation
    detection based on the current signal of the transducer is a useful method to
    detect cavitation in harsh environments and without perturbing the sound field.
    Once appli- cable indicators have been identified, they may easily be tracked
    during the process. However, for more detailed studies about the cavitation activity
    and its spatial distribution, measurements with in situ sensors are recommended.

  text: Nowadays wire bonding is a widely-used technology for interconnecting chips
    in the packaging industry. Thereby, it is known that the bond quality massively
    depends upon the microstructure prevailing in the bond and consequently the materials
    used as well as the bonding parameters. However the actually used materials such
    as aluminum and gold are either characterized by comparibly poor conductivity
    or high costs, respectively. Due to its outstanding properties copper is a more
    attractive candidate. Still, a thorough investigation on the interrelationship
    between the material combinations, the processing parameters and the resulting
    microstructure for copper and aluminum wire bonding was not carried out yet. Depending
    on the aforementioned factors the microstructural evolution can be completely
    different during the bonding process. Therefore, this study focuses on the microstructural
    evolution of heavy copper and heavy aluminum wires bonded on copper substrates.
    The evolution of the wire microstructure as well as the wire-substrate-interface
    was investigated by scanning electron microscope in combination with electron
    backscatter diffraction and microhardness measurements. Various samples were extracted
    at different points of the bonding process, namely the as-received condition,
    after touchdown and after completed bonding. The results of the aluminum and copper
    wires were compared to each other in both longitudinal and transversal direction.
    It was found, that the two wire materials were completely different in the as-received
    condition regarding the grain size, the grain morphology, the texture and the
    microhardness. After touchdown the microstructure did not show significant changes
    in both materials, yet a strain-hardening was observed in the copper wire resulting
    from the touchdown force. When the bonding process was completed a different microstructure
    could be observed in both the wire as well as the layer for the materials investigated.
    Furthermore, a destinctive increase in the wire hardness could be found in case
    of copper, which was not observed for the aluminum wire. The ramifications between
    the two wire materials presented in this work will be discussed with the objective
    of optimizing the quality of the bonds.

  text: 'Wire bonding is the most common technology for connecting electronic components.
    Due to their efficiency bond interconnections made of copper wire are used for
    example in the aerospace and medical technology as well as in the fields of renewable
    energies. One of the main cost factors in the manufacturing process is the consumables
    like bonding tools. The technological transition to copper as wire material causes
    significant wear on the millimeter large effective contact area of the bonding
    tool. This wear leads to a loss by a factor of 30 of the number of reliable interconnections
    which can be produced by a single tool. To reduce setting-up time in the production
    and minimizing costs, an enlarged bonding tool lifetime is desirable. Consequently
    a better understanding of wear and recognition of wear pattern is required. Therefore,
    the paper presents an analyzing method of the tool topography change of a heavy
    wire bonding tool by using a confocal microscope. Furthermore, the paper discusses
    the identification of the main wear indicators by the help of the named topography
    change for different bond parameters, like ultrasonic power and tool geometry.
    Reference topography has been carried out by choosing typical parameters of the
    production line. To judge whether the quality requirement of the bond connections
    made by a single tool cannot be fulfilled shear test of the source bond have been
    carried out after a defined number of produced bond connections. Main steps of
    analysis: (I)Topography of the tool surface is sampled after a defined number
    of bonds by means of a confocal microscope to detect the wear progress.(II)The
    recorded data is filtered using Matlab. So, measurement errors can be eliminated
    and the topography can be overlaid more easy to identify differences between diverse
    tools or differences in wear stages of the same tool.(III)The subsequent discretization
    of the topography into sub volumes allows to (IV)describe the loss of volume depending
    on the position in the groove. Thereby, intermediate status of wear of one tool
    can be used to obtain a persistent description of the topography change over the
    number of produced bonds by interpolating the confocal data. Afterwards the persistent
    change of the groove flank has been analyzed for the named test series to identify
    the main wear indicators and their effect on shear forces. All worn tools show
    dominant areas for volume loss especially for plastic deformation and accordingly
    abrasion. These wear mechanism can be referred to the change of main parts of
    the groove geometry like the rounding of the front and back radius. The most volume
    loss was identified in the upper part of the tool flanks or rather at the transition
    from the groove flank to the front or back radius. Furthermore the observation
    of the center of the groove flank shows just a little change in volume. All in
    all, the identification of the wear indicators will be discussed with the objective
    of increasing the tool lifetime by optimizing the tool geometry without losses
    in bond quality and reliability.'

  text: Intelligent technical systems, which combine mechanical, electrical and software
    engineering with methods from control engineering and advanced mathematics, go
    far beyond the state of the art in mechatronics and open up fascinating perspectives.
    Among these systems are so-called self-optimizing systems, which are able to adapt
    their behavior autonomously and flexibly to changing operating conditions. The
    Collaborative Research Center 614 "Self-optimizing concepts and structures in
    mechanical engineering" pursued the long-term aim to enable others to develop
    dependable self-optimizing systems. Assuring their dependability poses new challenges.
    However, self-optimization also offers the possibility to adapt the system's behavior
    to improve dependability during operation. The aim of this book is to provide
    methods and techniques to master the challenges and to exploit the possibilities
    given by self-optimization. The reader will be able to develop self-optimizing
    systems that fulfill and surpass today’s dependability requirements easily. This
    book is directed to researchers and practitioners alike. It gives a brief introduction
    to the holistic development approach for self-optimizing mechatronic systems and
    the steps required to assure a dependable product design starting with the very
    early conceptual design phase. A guideline to select suitable methods for each
    step and the methods themselves are included. Each method is individually introduced,
    many examples and full references are given.

  text: Piezoelectric inertia motors use the inertia of a body to drive it by means
    of a friction contact in a series of small steps. It has been shown previously
    in theoretical investigations that higher velocities and smoother movements can
    be obtained if these steps do not contain phases of stiction (''stick-slip`` operation),
    but use sliding friction only (''slip-slip`` operation). One very promising driving
    option for such motors is the superposition of multiple sinusoidal signals or
    harmonics. In this contribution, the theoretical results are validated experimentally.
    In this context, a quick and reliable identification process for parameters describing
    the friction contact is proposed. Additionally, the force generation potential
    of inertia motors is investigated theoretically and experimentally. The experimental
    results confirm the theoretical result that for a given maximum frequency, a signal
    with a high fundamental frequency and consisting of two superposed sine waves
    leads to the highest velocity and the smoothest motion, while the maximum motor
    force is obtained with signals containing more harmonics. These results are of
    fundamental importance for the further development of high-velocity piezoelectric
    inertia motors.

  text: (K,Na)NbO3 ceramics have attracted much attention as lead-free piezoelectric
    materials with high piezoelectric properties. High-quality (K,Na)NbO3 ceramics
    can be sintered using KNbO3 and NaNbO3 powders synthesized by a hydrothermal method.
    In this study, to enhance the quality factor of the ceramics, high-power ultrasonic
    irradiation was employed during the hydrothermal method, which led to a reduction
    in the particle size of the resultant powders.

  text: Application of prognostics and health management (PHM) in the field of Proton
    Exchange Membrane (PEM) fuel cells is emerging as an important tool in increasing
    the reliability and availability of these systems. Though a lot of work is currently
    being conducted to develop PHM systems for fuel cells, various challenges have
    been encountered including the self-healing effect after characterization as well
    as accelerated degradation due to dynamic loading, all which make RUL predictions
    a difficult task. In this study, a prognostic approach based on adaptive particle
    filter algorithm is proposed. The novelty of the proposed method lies in the introduction
    of a self-healing factor after each characterization and the adaption of the degradation
    model parameters to fit to the changing degradation trend. An ensemble of five
    different state models based on weighted mean is then developed. The results show
    that the method is effective in estimating the remaining useful life of PEM fuel
    cells, with majority of the predictions falling within 5\% error. The method was
    employed in the IEEE 2014 PHM Data Challenge and led to our team emerging the
    winner of the RUL category of the challenge.

  text: With the paradigm shift towards prognostic and health management (PHM) of
    machinery, there is need for reliable PHM methodologies with narrow error bounds
    to allow maintenance engineers take decisive maintenance actions based on the
    prognostic results. Prognostics is mainly concerned with the estimation of the
    remaining useful life (RUL) or time to failure (TTF). The accuracy of PHM methods
    is usually a function of the features extracted from the raw data obtained from
    sensors. In cases where the extracted features do not display clear degradation
    trends, for instance highly loaded bearings, the accuracy of the state of the
    art PHM methods is significantly affected. The data which lacks clear degradation
    trend is referred to as non-trending data. This study presents a method for extracting
    degradation trends from non-trending condition monitoring data for RUL estimation.
    The raw signals are first filtered using a discrete wavelet transform (DWT) denoising
    filter to remove noise from the acquired signals. Time domain, frequency domain
    and time-frequency domain features are then extracted from the filtered signals.
    An autoregressive model is then applied to the extracted features to identify
    the degradation trends. Features representing the maximum health information are
    then selected based on a performance evaluation criteria using extreme learning
    machine (ELM) algorithm. The selected features can then be used as inputs in a
    prognostic algorithm. The feasibility of the method is demonstrated using experimental
    bearing vibration data. The performance of the method is evaluated on the accuracy
    of RUL estimation and the results show that the method can be used to accurately
    estimate RUL with a maximum error of 10\%.

  text: The increasing demand for high reliability, safety and availability of technical
    systems calls for innovative maintenance strategies. The use of prognostic health
    management (PHM) approach where maintenance action is taken based on current and
    future health state of a component or system is rapidly gaining popularity in
    the maintenance industry. Multiclass support vector machines (MC-SVM) has been
    identified as a promising algorithm in PHM applications due to its high classification
    accuracy. However, it requires parameter tuning for each application, with the
    objective of minimizing the classification error. This is a single objective optimization
    problem which requires the use of optimization algorithms that are capable of
    exhaustively searching for the global optimum parameters. This work proposes the
    use of hybrid differential evolution (DE) and particle swarm optimization (PSO)
    in optimally tuning the MC-SVM parameters. DE identifies the search limit of the
    parameters while PSO finds the global optimum within the search limit. The feasibility
    of the approach is verified using bearing run-to-failure data and the results
    show that the proposed method significantly increases health state classification
    accuracy.

  text: An automotive suspension system represents one of the most complex and important
    systems in a passenger vehicle, which has to ensure a robust and optimized contact
    between the wheels and the road at any time. For improving a suspension system
    it is important to take an investigative look at the interaction between suspension,
    tire and road dynamics. Thus a part of a study into aspects of suspension modeling
    on multi-body simulations of rear multi-link suspension system dynamics with focus
    on the tire footprint area is presented in this work.

  text: So-called reliability adaptive systems are able to adapt their system behavior
    based on the current reliability of the system. This allows them to react to changed
    operating conditions or faults within the system that change the degradation behavior.
    To implement such reliability adaptation, self-optimization can be used. A self-optimizing
    system pursues objectives, of which the priorities can be changed at runtime,
    in turn changing the system behavior. When including system reliability as an
    objective of the system, it becomes possible to change the system based on the
    current reliability as well. This capability can be used to control the reliability
    of the system throughout its operation period in order to achieve a pre-defined
    or user-selectable system lifetime. This way, optimal planning of maintenance
    intervals is possible while also using the system capabilities to their full extent.
    Our proposed control system makes it possible to react to changed degradation
    behavior by selecting objectives of the self-optimizing system and in turn changing
    the operating parameters in a closed loop. A two-stage controller is designed
    which is used to select the currently required priorities of the objectives in
    order to fulfill the desired usable lifetime. Investigations using a model of
    an automotive clutch system serve to demonstrate the feasibility of our controller.
    It is shown that the desired lifetime can be achieved reliably.
