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: 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.
