Article
Full-text available
Fused filament fabrication (FFF), an additive manufacturing process, is an emerging technology with issues in the uncertainty of mechanical properties and quality of printed parts. The consideration of all main and interaction effects when changing print parameters is not efficiently feasible, due to existing stochastic dependencies. To address thi...
Chapter
Aus dem Vorwort: Durch die zunehmende Digitalisierung und Vernetzung, beispielsweise in einer Smart Factory im Kontext von Industrie 4.0, werden hohe Anforderungen an die Zuverlässigkeit, die Verfügbarkeit und die Sicherheit von Maschinen und Anlagen gestellt. Dies erfordert den konsequenten Einsatz und die ständige Weiterentwicklung von Methoden u...

Bei Messungen des Schallabsorptionsgrades von Schaumstoffen in einem Kundt’schen Rohr treten unerwartete Einflüsse von Störgrößen auf. Es konnte in vorangegangenen Studien gezeigt werden, dass Störgrößen wie beispielsweise Formabweichungen, der Einsatz unterschiedlicher Fertigungsverfahren und die fertigende Person systematische Einflüsse auf den g...
Article
Scaling laws are used to scale-up calculation or measurement results from a prototype structure to those of an original structure or vice versa. The scaling laws of mechanical structures are usually obtained from their equations of motion or from a dimensional analysis. This paper proposes scaling laws that are represented by a power law. The power...
Article
Full-text available
The active approach is nowadays well developed and widely used for various kinds of structures for vibration control or compensation. However, it makes the structure more complex than a passive structure. In this study, active and passive beam structures with the same designed size are compared with regard to uncertainty analysis of the system. The...
Chapter
A smart structure is a structure that can reduce a structural vibration by means of the integration of one or more sensor, actuator, and controller. A sensor detects a vibration in the structure and transfers a signal to a controller. The controller, designed to compensate the structural vibration, then computes the desired control signal and sends...

Conference Paper
Full-text available
Scaling laws are a powerful tool for vibroacoustic analyses that utilize a scaled model instead of the original structure, i.e., noise and vibration responses are obtained from a prototype structure and are subsequently transferred to the original by using the scaling law. Recent research activities show that scaling laws can directly be obtained f...
Chapter
Die Sicherstellung einer von Kundenseite gewünschten hohen Zuverlässigkeit erfordert im Zeitalter der Industrie 4.0 und der zunehmenden Komplexität der Systeme eine ständige Weiterentwicklung bekannter Ansätze. Letztendlich muss die Zuverlässigkeit eines Produktes über den gesamten Produktlebenslauf betrachtet werden und beherrschbar sein. Derzeiti...
Article
In the present work the bubble diameter, heater surface temperature distribution, and local heat flux during different stages of single bubble cycles during pool boiling of PF-5060 at a pressure of p = 600 mbar have been investigated in several stable low g levels during the 1st Joint European Partial-g Parabolic Flight (JEPPF) Campaign. In previou...
Article
The present study reports on nucleate boiling tests performed with specifically textured chromium nitride (CrN) coatings exhibiting either predominant (1 1 1), (2 0 0) or (2 2 0) crystal lattice orientations. Those tests reveal promising results concerning thin film applications in the field of heat transfer enhancement during nucleate boiling. Hig...

Full-text available
In the present work, the influence of micro-structured chromium nitride (CrN) surfaces on boiling heat transfer during nucleate boiling of FC-72 at saturation temperature was investigated. The CrN thin coatings of 4.5 μm thickness in average were deposited by Physical Vapor Deposition (PVD) as a combination of High Power Impulse Magnetron Sputterin...
Article
In the present work the behavior of single vapor bubbles of FC-72, generated on a thermal capacitive heater element, has been investigated during microgravity. A newly developed heater design allows temperature measurements by highspeed infrared thermography on the backside of the heater surface at a distance of approx. 800 nm from the fluid/heate...
Book
Inhalt des vorliegenden Buches ist die Darstellung der Entwicklung und Umsetzung eines Vorgehenskonzepts für die Einführung von Projektmanagement-Standards in der werkstofftechnischen Forschung und Materialprüfung. In Form eines Pilotprojekts wurde ein Konzept zur nachhaltigen und mitarbeiterfreundlichen Implementierung von Projektmanagement erarbe...
Article
Imperfection on substrate surfaces commonly causes growth defects in hard coatings prepared by magnetron sputtering, leading to local loss of adhesion, higher friction, voids and corrosion at coating defects. CrN coatings are known for their high hardness and good wear resistance. The structure and the mechanical properties of those coatings can be...
Article
Störstellen in Bauteiloberflächen wirken sich häufig ungünstig auf die Schichtnukleation bei PVD-Beschichtungen aus. Sie können beim Schichtwachstum zu defekten in der Schichtstruktur führen. Die Konsequenz ist eine Minderung der lokalen Haftfestigkeit, höhere Reibwerte und Fehlstellen in der Schicht. Diese begünstigen in korrosiven Medien die Ents...
