abstract = {{Piezoelektrische Trägheitsmotoren nutzen die Trägheit einer bewegten Masse, um diese über einen ununterbrochenen Reibkontakt schrittweise zu bewegen. Wegen ihres einfachen Aufbaus und ihrer guten Miniaturisierbarkeit werden diese Motoren zunehmend in Konsumgütern eingesetzt. Die Geschwindigkeit ist eine wichtige Motorkenngröße, eine allgemeingültige Analyse des Motorprinzips existiert jedoch bisher nicht.Nach einer Definition von Trägheitsmotoren werden anhand eines Modells eines translatorischen piezoelektrischen Trägheitsmotors verschiedene idealisierte Anregungssignale hergeleitet. Eine Analyse des Motorverhaltens zeigt, dass der verbreitete Betrieb von Trägheitsmotoren mit Haft- und Gleitphasen für das Erreichen hoher Geschwindigkeiten ungeeignet ist. Aus den idealisierten Signalen für den schnellen dauergleitenden Betrieb werden frequenzbeschränkte Signale für den Betrieb mit realen Aktoren abgeleitet. Das Verhalten bei Anregung mit diesen Signalen wird bezüglich Geschwindigkeit, Effizienz, Haltbarkeit und Kraft verglichen. Zudem wird ein Verfahren beschrieben, mit dem die Bewegung hochfrequent angeregter Trägheitsmotoren periodenweise berechnet und wichtige Motorkenngrößen direkt berechnet werden können. Zur Validierung der theoretischen Ergebnisse wird ein Versuchsmotor aufgebaut und mit unterschiedlichen Signalen angeregt, es zeigt sich eine gute Übereinstimmung zwischen Messung und Modell. Die Ergebnisse dieser Arbeit geben wertvolle Einblicke in die Funktion schneller Trägheitsmotoren und sind nützlich für ihre weitere Entwicklung und die Erweiterung ihres Einsatzbereichs.}},

abstract = {{The reproducibility and reliability of quality aspects are an important challenge of the polymer laser sintering process. However, existing quality concepts and standardization activities considering influencing factors along the whole process chain have not been validated experimentally yet. In this work, these factors are analyzed and kept constant to obtain a reliable material data set for different layer thicknesses and testing temperatures. In addition, material qualities regarding powder ageing effects are analyzed using different build heights and layer thicknesses: while an increase of the layer thickness reduces mechanical part strength and density, it also results in a less intense thermal ageing of unmolten powder due to shorter build times.}},

abstract = {{In order to achieve a sustainable competitive advantage, technology-oriented companies are more than ever asked to identify potentials of technologies for future business at an early stage and to convert them into innovations. Emergent technologies in particular have a high potential for radical innovations. However, the high innovation potential is offset by high market and technology uncertainties, which are caused by incomplete knowledge of the technology potential and development as well as of potential application contexts. In connection with emergent technologies, the finding of potential - i.e. the generation of knowledge regarding the potentials - is essential, as it lays the foundation for the search for potential application contexts. At the same time, this represents a challenge, since conventional market research approaches only have a limited effect here. The question that arises is how technology potentials can be derived in a discursive way. Furthermore, we hypothesize that the TRIZ approach has great potential for this: (1) In a reversal of the TRIZ logic, we see a way of accessing the TRIZ knowledge base via an analogy; (2) In this way, contradictions within the meaning of TRIZ can be determined, which can be addressed by the technology; (3) A continuous specification of the contradictions represents a possibility to infer technology potentials. The present article presents an approach developed at the Heinz Nixdorf Institute for a TRIZ-based potential finding within the framework of technology-induced innovation processes. The approach comprises the three phases of technology analysis, technology foresight and technology potential analysis. Based on the analysis of the current performance of the technology, the future performance is anticipated using the TRIZ development pattern. By reversing the TRIZ logic, technology potentials are finally determined.

Often, however, companies are faced with two core problems when introducing product innovations to the market: There is a lack of a methodology for systematic customer integration in the product development process. In addition, due to their complexity and the novelty of the technologies used, the product concepts exceed the customers' imagination. This means that customers do not evaluate new product concepts objectively because they do not fully understand the product benefits. In this article, a software-supported procedure for early customer integration is presented. The core of the process is a multi-stage limit conjoint analysis with an integrated virtual reality application.}},

abstract = {{Innovative products are based on an interdisciplinary interaction between mechanics, electronics and information technology. The close interplay of the specialist disciplines makes special demands on the development process. For example, a uniform understanding of the specialists is particularly important for an efficient development of the product and the associated production system. Furthermore, the product concept often already determines the production system, even though new production technologies make innovative products possible in the first place. Therefore, the interactions between the product and the production system must be taken into account from the start during development. Currently, the development is mostly carried out separately in the specialist disciplines on the basis of existing methods and systematics, who often do not fully consider the existing interactions. Time-consuming and costly iteration loops are the result. This article therefore addresses the interactions and mutual dependencies between the product and the production system in the early phases of product development, such as an adaptation of the product design due to assembly requirements. The development process of a flashlight serves as an example. First, the interactions are described and analyzed. A methodology is then presented that takes these interactions into account in the context of the integrative development of product and production system in the early phases of product development. The methodology consists of a process model, a specification technique and a software tool. The process model serves as a guideline for the integrative development of product and production system, whereas the specification technology forms the core of the methodology and enables interdisciplinary collaboration of all people involved. For the product concept, the specification technology encompasses the aspects of the environment, application scenarios, requirements, functions, effective structure, behavior and design. The principle solution of the production system is represented by the aspects of production requirements, process sequence, resources and design. The software tool supports the developer in applying the methodology. The methodology presented is then demonstrated using the example product. whereas the specification technology forms the core of the methodology and enables interdisciplinary collaboration of all people involved.

abstract = {{SUMMARYWe introduce a material model for the simulation of polycrystalline materials undergoing solid‐to‐solid phase‐transformations. As a basis, we present a scalar‐valued phase‐transformation model where a Helmholtz free energy function depending on volumetric and deviatoric strain measures is assigned to each phase. The analysis of the related overall Gibbs energy density allows for the calculation of energy barriers. With these quantities at hand, we use a statistical‐physics‐based approach to determine the resulting evolution of volume fractions. Though the model facilitates to take into account an arbitrary number of solid phases of the underlying material, we restrict this work to the simulation of phase‐transformations between an austenitic parent phase and a martensitic tension and compression phase. The scalar model is embedded into a computational micro‐sphere formulation in view of the simulation of three‐dimensional boundary value problems. The final modelling approach necessary for macroscopic simulations is accomplished by a finite element formulation, where the local material behaviour at each integration point is governed by the response of the micro‐sphere model.Copyright © 2014 John Wiley & Sons, Ltd.}},
