text: 'Several positioning tasks demand translatory drive instead of rotary motion.
To achieve drives that are capable, e.g., to drive the sunroof of a car or to
lift a car''s window, multiple miniaturized motors can be combined. But in this
case many other questions arise: The electromechanical behavior of the individual
motors differs slightly, the motor characteristics are strongly dependent on the
driving parameters and the driven load, many applications need some extra power
for special cases like overcoming higher forces periodically. Thus, the bundle
of motors has to act well-organized and at last controlled to get an optimized
drive that is not oversized and costly.'

text: 'Integrating dependability in self-optimizing systems is a challenging task.
Self-optimizing systems incorporate on the one hand the opportunity to apply novel
solutions to complex mechatronic systems, but on the other hand constitute a possible
risk because of non-determined behavior. The dependability concept in this paper
covers both aspects: Increasing safety with selfoptimization and minimizing the
risk of self-optimization. This dependability concept is combined with the self-optimization
process of the active guidance module which is currently under development at
the Collaborative Research Center 614 at the University of Paderborn.'

text: For devices having non-linear contact, load plays a fundamental role. Variations
in the characteristics of the load cause change in eigenfrequency and amplitude
of the vibration. In most technical applications, this unwanted behaviour is cancelled
by the use of control algorithms. However, multiple applications, like bond quality
monitoring or chemical and pressure sensors, have found that the load may be characterised
by interpreting the change in characteristics of a resonant vibrating device used
as a sensor. Surgical resection of tumours is a very difficult task. After localising
the tumour by the use of imaging techniques, the resection demands the surgeon
to decide where and what to resect based on visual and tactile differentiation
of tumour and healthy tissue. Exactness of this process could be enhanced if we
can provide the surgeon with a device capable of evaluating mechanical characteristics
of the tissue much more accurately than the surgeon himself can do. As the mechanical
characteristics of tumour and healthy tissue differ but slightly, the task is
to design a system with high sensitivity. Therefore, we have developed a resonant
actuator-sensor that allows the differentiation among distinct media that have
similar mechanical characteristics to tumour and healthy tissue using a piezoelectric
bimorph. The design is based on the detection and evaluation of frequency shift
and amplitude variation of the fundamental and higher harmonics using one layer
for the resonant excitation of vibration and the other one as the sensing element.

text: Many ultrasonic processes are based on the mechanical contact of oscillating
parts. Within ultrasonic machining (drilling, milling, grinding) micro impacts
lead to abrasion at the processed workpiece and hopefully do not damage the tool.
In ultrasonic motors ideally neither part gets worn. Thus the appropriate design
of contact partners as well as their kinematics is a substantial task during the
development of such devices. A first step to optimize contact mechanics is to
understand their behavior and dependencies on parameter variations, such as vibration
amplitude and pre-stress of the impacting parts. For a detailed understanding
models validated with convincing experimental data from measurements are absolutely
essential. This paper focuses on simple vibro-impact experiments which can be
used as benchmark data for future models. The setup of the experiment and first
experimental investigations are described in detail.

text: Penetration tests (Magness-Taylor, force/deformation, Kramer multiblade shear)
applied directly over the peel of the fruit are the most acceptable methods for
measuring firmness and turgidity of fruits and vegetables [1, 2]. To replace these
destructive and mechanical penetration methods by non-destructive ultrasonic measurements
implies a great advance in order to obtain fast studies about the state of the
fruit at the time of harvest, during storage, and in the distribution points.
Moreover, there are other advantages since this technique can be fast, non-destructive,
fully automated, and performed on-line [1]. Within this context, the objective
of this study was to examine the relationship between physico-mechanical characteristics
(oil-gland break stress, thickness and dehydration) and ultrasonic characteristics
in the ``Salustiana'' orange peel during the complete dehydration process of the
orange at ambient conditions. After a description of the measurement system [3],
the fruit selection procedure and the measurement protocol, we analyze the results
of the change of physico-mechanical and ultrasonic properties in the orange peel
and their change with storage time.

text: 'Surgical resection of brain tumours is a difficult task. To enhance surgery
results, a tactile sensor is wanted that gives better resolution and sensitivity
than the human tactile sense. The characteristics of resonant vibrating piezoelectric
elements change with varying load. This allows for calculation of mechanical load
parameters by measuring electrical quantities. Different setups of piezoelectric
sensors have been used to investigate soft materials. Finally, a piezoelectric
bimorph sensor gave good results for distinguishing tissue mimicking gel-phantoms
with different gelatine concentrations. '

text: Numerical predictions of the forced vibration of a disk assembly including
frictional effects between the shrouds are presented concerning engineering needs
for the blade design process. Assuming a tuned disk assembly, numerical static,
free, and then forced vibration analyses of a shrouded turbine blade measured
in the spin pit are performed systematically. For the excitation forces of an
air jet evaluated from the fairly linear behavior of the experimental blade resonance
peaks, the reliability of the proposed approach is validated through the very
close agreement of the computed and measured resonant peaks. These resonant peaks
demonstrate either a fairly linear behavior or a nonlinear one like the jump effect
of blade resonance amplitudes, or elastic impacts between the shrouds. Also, the
damping performance for different contact configurations between the shrouds is
numerically analyzed. These numerical results indicate that the shrouds generate
higher frictional damping for small angles (0{\^a}30deg) between the circumferential
direction and the normal vector to the contact surface.

text: 'The design of piezoelectric transducers is usually based on single-objective
optimization only. In most practical applications of piezoelectric transducers,
however, there exist multiple design objectives that often are contradictory to
each other by their very nature. It is impossible to find a solution at which
each objective function gets its optimal value simultaneously. Our design approach
is to first find a set of Pareto-optimal solutions, which can be considered to
be best compromises among multiple design objectives. Among these Pareto-optimal
solutions, the designer can then select the one solution which he considers to
be the best one. In this paper we investigate the optimal design of a Langevin
transducer. The design problem is formulated mathematically as a constrained multiobjective
optimization problem. The maximum vibration amplitude and the minimum electrical
input power are considered as optimization objectives. Design variables involve
continuous variables (dimensions of the transducer) and discrete variables (the
number of piezoelectric rings and material types). In order to formulate the optimization
problem, the behavior of piezoelectric transducers is modeled using the transfer
matrix method based on analytical models. Multiobjective evolutionary algorithms
are applied in the optimization process and a set of Pareto-optimal designs is
calculated. The optimized results are analyzed and the preferred design is determined. '

text: This paper presents a model for unsteady longitudinal slippage of a loaded
rubber wheel. The aim of modelling was to calculate the dynamical contact behavior
in a numerical efficient way. Further on, simulation results are compared to experimental
