text: This paper presents the results of an interlaboratory study of the rheological
properties of cement paste and ultrasound gel as reference substance. The goal
was to quantify the comparability and reproducibility of measurements of the Bingham
parameters yield stress and plastic viscosity when measured on one specific paste
composition and one particular ultrasound gel in different laboratories using
different rheometers and measurement geometries. The procedures for both in preparing
the cement paste and carrying out the rheological measurements on cement paste
and ultrasound gel were carefully defined for all of the study’s participants.
Different conversion schemes for comparing the results obtained with the different
measurement setups are presented here and critically discussed. The procedure
proposed in this paper ensured a reasonable comparability of the results with
a coefficient of variation for the yield stress of 27% and for the plastic viscosity
of 24%, despite the individual measurement series’ having been performed in different
labs with different rheometers and measurement geometries.

text: Since suspensions (e.g., in food, cement, or cosmetics industries)
tend to show wall slip, the application of structured measuring surfaces in rheometers
is widespread. Usually, for parallel-plate geometries, the tip-to-tip distance
is used for calculation of absolute rheological values, which implies that there
is no flow behind this distance. However, several studies show that this is not
true. Therefore, the measuring gap needs to be corrected by adding the effective
gap extension δ to the prescribed gap height H in order to obtain
absolute rheological properties. In this paper, we determine the effective gap
extension δ for different structures and fluids (Newtonian, shear thinning,
and model suspensions that can be adjusted to the behavior of real fluids) and
compare the corrected values to reference data. We observe that for Newtonian
fluids a gap- and material-independent correction function can be derived for
every measuring system, which is also applicable to suspensions, but not to shear
thinning fluids. Since this relation appears to be mainly dependent on the characteristics
of flow behaviour, we show that the calibration of structured measuring systems
is possible with Newtonian fluids and then can be transferred to suspensions up
to a certain particle content.

text: Wall slip is a long-known phenomenon in the field of rheology. Nevertheless,
the origin and the evolution are not completely clear yet. Regarding suspensions,
the effect becomes even more complicated, because different mechanisms like pure
slip or slip due to particle migration have to be taken into account. Furthermore,
suspensions themselves show many flow anomalies and the isolation of slip is complicated.
In order to develop working physical models, further insight is necessary. In
this work, we measured experimentally the wall slip velocities of different highly
filled suspensions in a rectangular slit die directly with respect to the particle
concentration and the particle size. The slip velocities were obtained using a
particle image velocimetry (PIV) system. The suspensions consisting of a castor
oil–cinnamon oil blend and PMMA particles were matched in terms of refractive
indexes to appear transparent. Hereby, possible optical path lengths larger than
15 mm were achieved. The slip velocities were found to be in a quadratic relation
to the wall shear stress. Furthermore, the overall flow rate as well as the particle
concentration has a direct influence on the slip. Concerning the shear stress,
there seem to be two regions of slip with different physical characteristics.
Furthermore, we estimated the slip layer thickness directly from the velocity
profiles and propose a new interpretation. The PIV technique is used to investigate
the viscosity and implicit the concentration profile in the slit die. It is shown
that the particle migration process is quite fast.

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: 'Piezoelectric inertia motors, also known as ``stick--slip drives'''', use
the inertia of a body to drive it in small steps by means of a friction contact.
While these steps are classically assumed to involve stiction and sliding, the
motors can also operate in ``slip--slip'''' mode without any phase of static friction.
This contribution provides a systematic investigation and performance comparison
of different stick--slip and slip--slip modes of operation. Different criteria
for comparing the motional performance of inertia motors are defined: Steady state
velocity, smoothness of motion, and start-up time. Using the example of a translational
inertia motor excited by an ideal displacement signal, it is found that the maximum
velocity reachable in stick--slip operation is limited principally, while continuous
slip--slip operation allows very high velocities. For the investigated driving
signals, the motor velocity is proportional to the square root of the actuator
stroke. The motor performance with these ideal signals defines an upper boundary
for the performance of real motors.'

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. These motors can operate in
``stick-slip'' or ``slip-slip'' mode, with the fundamental frequency of the driving
signal ranging from several Hertz to more than 100 kHz. To predict the motor characteristics,
a Coulomb friction model is sufficient in many cases, but numerical simulation
requires microscopic time steps. This contribution proposes a much faster simulation
technique using one evaluation per period of the excitation signal. The proposed
technique produces results very close to those of timestep simulation for ultrasonics
inertia motors and allows direct determination of the steady-state velocity of
an inertia motor from the motion profile of the driving part. Thus it is a useful
simulation technique which can be applied in both analysis and design of inertia
motors, especially for parameter studies and optimisation.

text: Piezoelectric inertia motors, also known as ``stick-slip-drives'', use the
inertia of a body to drive it by means of a friction contact in small steps. While
these steps normally involve stiction and sliding, the motors can also operate
in ``slip-slip'' mode without any phase of static friction. In this contribution,
a one degree of freedom model of an inertia motor driven by an ideal actuator
is analysed. Start-up and constant velocity operation of the motor are investigated
and appropriate quantities to compare ``stick-slip'' and ``slip-slip'' operation
are determined. Different aspects such as velocity, uniformity of motion, load
capacity, robustness, efficiency, and wear are considered. The analysis allows
both modes to be applied advantageously in different applications and can widen
the field of application of piezoelectric inertia motors. Motor designers are
enabled to choose the appropriate mode of operation and the best drive parameters
for their individual applications.
