This allows for miniaturization and low cost production. One of the main questions to be answered during the design process of a piezoelectric inertia motor is which electrical excitation signal yields optimum motor characteristics. Three signals and their variants are widely used in literature: sawtooth, parabolic and cycloidic signals. It can be shown that neither of these can drive the motor at its maximum possible velocity in non-resonant operation. Within this paper we propose to use a rigid body model of a simple inertia motor to predict the motor characteristics depending on the movement pattern of the driving element. Advantages and disadvantages of three different drive signals that maximize the motor velocity are discussed.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Journal of Korean Physical Society"},{"user_id":"55222","department":[{"_id":"151"}],"_id":"9752","language":[{"iso":"eng"}],"type":"journal_article","publication":"Journal of Korean Physical Society","status":"public","abstract":[{"lang":"eng","text":"Piezoelectric inertia motors make use of the inertia of a slider to drive the slider by friction contact in a series of small steps which are generally composed of a stick phase and a slip phase. If the best electrical drive signal for the piezoelectric actuator in an inertia motor is to be determined, its dynamical behaviour must be known. A classic dynamic lumped parameter model for piezoelectric actuators is valid only in resonance and, therefore, is not suitable for modelling the actuator in an inertia motor. A reduced dynamic model is used instead. Its parameters are identified using a step response measurement. This model is used to predict the movement of the actuator in response to a velocity-optimized signal introduced in a separate contribution. Results show that the model cannot represent the dynamical characteristics of the actuator completely. For determining voltage signals that let piezoelectric actuators follow a calculated movement pattern exactly, the model can, therefore, only be used with limitations."}],"author":[{"last_name":"Hunstig","full_name":"Hunstig, Matthias","first_name":"Matthias"},{"last_name":"Hemsel","full_name":"Hemsel, Tobias","id":"210","first_name":"Tobias"}],"date_created":"2019-05-13T10:04:13Z","volume":57,"date_updated":"2022-01-06T07:04:19Z","doi":"10.3938/jkps.57.952","title":"Parameter Identification and Model Validation for the Piezoelectric Actuator in an Inertia Motor","issue":"4","publication_identifier":{"issn":["1948-5719"]},"quality_controlled":"1","citation":{"chicago":"Hunstig, Matthias, and Tobias Hemsel. “Parameter Identification and Model Validation for the Piezoelectric Actuator in an Inertia Motor.” <i>Journal of Korean Physical Society</i> 57, no. 4 (2010): 952–54. <a href=\"https://doi.org/10.3938/jkps.57.952\">https://doi.org/10.3938/jkps.57.952</a>.","ieee":"M.

Eine Kernfrage bei der Entwicklung eines piezoelektrischen Trägheitsmotors ist, welches elektrische Ansteuersignal für das gewünschte Motorverhalten optimal ist. Das elektrische Signal führt zu einer Bewegung des piezoelektrischen Aktors und damit der Antriebsstange, die den reibschlüssigen Vortrieb bewirkt. Entsprechend wird diese Fragestellung in zwei Teilen untersucht: Anhand eines Starrkörpermodells werden zunächst Bewegungsverläufe für die Antriebsstange ermittelt, mit denen die maximale Geschwindigkeit erreicht wird. Dabei werden drei Antriebsmodi identifiziert. Mit allen kann eine höhere Geschwindigkeit als mit der heute häufig verwendeten Sägezahnanregung erreicht werden. Anschließend wird ein einfaches dynamisches Modell eines piezoelektrischen Aktors genutzt, um die notwendigen elektrischen Ansteuersignale für die verschiedenen Antriebsmodi zu bestimmen. Es zeigt sich, dass das gewählte einfache Modell hierzu nur bedingt geeignet ist.","lang":"eng"}]},{"title":"Improving the Performance of Piezoelectric Inertia Motors","date_updated":"2022-01-06T07:04:19Z","author":[{"last_name":"Hunstig","full_name":"Hunstig, Matthias","first_name":"Matthias"},{"id":"210","full_name":"Hemsel, Tobias","last_name":"Hemsel","first_name":"Tobias"},{"last_name":"Sextro","full_name":"Sextro, Walter","id":"21220","first_name":"Walter"}],"date_created":"2019-05-13T10:10:31Z","year":"2010","page":"657-661","citation":{"apa":"Hunstig, M., Hemsel, T., &#38; Sextro, W.

Als Schwerpunkt wird anschließend deren analytische Berechnung und messtechnische Verifizierung an typischen Beispielen demonstriert.

This paper presents a guideline for the dependability-oriented design of self-optimizing systems, which integrates established classical methods like failure mode and effects analysis as well as methods based on self-optimization. On the one hand self-optimization is used to increase the dependability of the system by integrating objectives like safety, availability, and reliability to the objectives of the system. On the other hand methods are required to ensure the self-optimization itself. As basis for this guideline serves the principle solution of the system. The six phases of the guideline extend the design process and lead to an enhanced principle solution. Additionally, the guideline illustrates phases to implement and validate the self-optimizing system.

First test drives provide information for the enhancement of the implementation of realtime switching to appropriate control strategies. The different control strategies are investigated in detail. It is illustrated that influences on the system like different track sections or the desired velocity of the RailCab effect the system and can lead to a higher amount of flange contacts, which indicate higher wear and thus a reduction of the availability of the system.

In order to achieve crack-free GaN layers of\r\nreasonable thicknesses and dislocation densities it is crucial to integrate both dislocation reduction and strain management layers. In contrast to techniques like FACELO or nanoELO we show the in situ formation of GaN islands directly on the AlN nucleation layer without the need to deposit a SiO2 or SiNx mask. A graded AlGaN layer for strain management can be grown on top of this dislocation reducing 3D GaN inter-layer in order to achieve crack-free GaN layers grown on top of the AlGaN strain management layer. Furthermore, an additional SiNx layer for subsequent dislocation reduction can also be incorporated into the structure and is shown to efficiently reduce the dislocation density down to the low 10^9 cm^2. The structural properties of the 3D GaN island buffer layer and overgrown\r\nsamples are studied by means of SEM, cross-sectional, and plan view TEM. Cathodoluminiscence in an SEM is employed to correlate the dislocation microstructure as observed by plan view TEM with luminescent properties."}],"publication":"physica status solidi (b)","language":[{"iso":"eng"}],"ddc":["530"]},{"language":[{"iso":"eng"}],"department":[{"_id":"155"}],"user_id":"15164","_id":"13170","status":"public","publication":"International Journal of Refrigeration","type":"journal_article","doi":"10.1016/j.ijrefrig.2010.08.004","title":"Nucleate pool boiling, film boiling and single-phase free convection at pressures up to the critical state.

One of these additive manufacturing technologies is “Fused Deposition Modeling” (FDM). From a 3D-CAD data set, components and assemblies are manufactured out of thermoplastic material in only a few working steps. Native software automatically slices the data, calculates the support structures, and creates toolpaths. The parts then are built up layer by layer by means of an additive process. An extrusion head deposits the molten thermoplastic filament to create each layer. This technology began as a process for creating prototype parts; recently it has found new utility in the production of manufacturing tools and as a manufacturing process for end-use parts. In order to be used as a part for serial production, the components must possess the required mechanical properties. To this end, not only is the chosen material relevant, but a correct process control is also necessary. An interesting material for the aircraft and automotive industry is the material PEI with the trade name Ultem*9085. This material should typically be used on FDM-machines for the manufacturing of end products. The aim of the research is to determine the present mechanical data based on the process control, as well as reproducibility from job to job. In this work the influence of the orientation and the structure of the manufactured parts based on the mechanical data are analyzed. Sample parts are generated with the given parameters of the native software based upon the CAD data. First, specimens were analyzed concerning their geometry and configuration. The dimensions and weight were measured. The mechanical tests conducted were the tensile and compression tests."}],"status":"public","_id":"22050","department":[{"_id":"219"},{"_id":"624"},{"_id":"367"},{"_id":"9"}],"user_id":"70729","language":[{"iso":"eng"}]},{"user_id":"16220","series_title":"Kraichtaler Kolloquien","department":[{"_id":"446"}],"_id":"34948","language":[{"iso":"eng"}],"type":"book_chapter","publication":"Freiheit und Unfreiheit.
