Pulsed laser radiation is used to thermoacoustically excite broadband ultrasonic waves in a multi-layered sample, consisting of a metal plate adhesively joined to a polymeric layer using synthetic resin. The resulting signals are received by a purpose-built piezoelectric transducer. Varying the distance between excitation and detection yields spatio-temporal measurement data, from which the dispersive properties of the propagating waves can be inferred using a two-dimensional Fourier transform, assuming the plates to act as coupled waveguides. Coupled multi-layered waveguides show an effect referred to as mode repulsion, where the distance between certain modes in the frequency-wavenumber domain is assumed to be a measure of coupling strength. Measurements at different stages of curing of the adhesive layer are performed and evaluated. A comparison of the results shows changes in the dispersive properties, namely an increased modal bandwidth for the fully cured sample as well as an increased modal distance. author: - first_name: Henning full_name: Zeipert, Henning id: '32580' last_name: Zeipert - first_name: Leander full_name: Claes, Leander id: '11829' last_name: Claes orcid: 0000-0002-4393-268X - first_name: Sarah full_name: Johannesmann, Sarah id: '29190' last_name: Johannesmann - first_name: Yevgeniya full_name: Lugovtsova, Yevgeniya last_name: Lugovtsova - first_name: Marcel full_name: Nicolai, Marcel last_name: Nicolai - first_name: Jens full_name: Prager, Jens last_name: Prager - first_name: Bernd full_name: Henning, Bernd id: '213' last_name: Henning citation: ama: Zeipert H, Claes L, Johannesmann S, et al.

Neben der Absorption im Fluid treten dabei weitere Effekte (zum Beispiel Beugung oder unvollständige Reflexion) auf, die das akustische Signal schwächen oder anderweitig beeinflussen. Die Entwicklung von Verfahren zur Trennung dieser Effekte von der akustischen Absorption bildet daher einen weiteren Schwerpunkt dieser Arbeit.Abschließend wird die Volumenviskosität aus der gemessenen akustischen Absorption für unterschiedliche Fluide in verschiedenen thermodynamischen Zuständen unter Zuhilfenahme anderer bekannter Fluidkenngrößen bestimmt sowie eine Unsicherheitsbetrachtung durchgeführt. - lang: eng text: The prerequisite for a complete description of fluid dynamic and acoustic processes is that all properties of the fluid are known.While fluid parameters such as the speed of sound or the shear viscosity are known for many liquids over a wide range of thermodynamic states, only limited measurement data exist for the bulk viscosity.In this thesis, a measurement method for the selective determination of the bulk viscosity of liquids, based on the absorption of ultrasonic waves, is developed and implemented.The focus is on the simulation-driven design of algorithms for processing the measurement signals as well as the analysis and further development of a measurement set-up based on the pulse-echo method.In addition to absorption in the fluid, there are other effects (for example diffraction or incomplete reflection) that weaken or otherwise influence the acoustic signal.Therefore, the development of procedures to separate these effects from acoustic absorption is another focus of this work.The bulk viscosity is determined from the measured acoustic absorption for different fluids in different thermodynamic states. An uncertainty analysis of the measured quantities concludes this thesis. author: - first_name: Leander full_name: Claes, Leander id: '11829' last_name: Claes orcid: 0000-0002-4393-268X citation: ama: Claes L.

Dabei ist vor allem die Wahl der Materialparameter der verwendeten Materialien wichtig für ein realitätsnahes Simulationsergebnis. Bei Schallwandlern werden häufig Piezokeramiken als aktive Elemente genutzt, welche sich durch eine Verkopplung mechanischer und elektrischer Eigenschaften auszeichnen. Zur Bestimmung ihrer Materialparameter stellt der IEEE Standard on Piezoelectricity ein standardisiertes Verfahren dar. Dazu sind fünf Impedanzmessungen an vier unterschiedlich gefertigten Probekörpergeometrien notwendig. Da an jedem einzelnen Probekörper nur eine Untermenge aller notwendigen Materialparameter bestimmt werden kann, werden diese dann zu einem kompletten Materialparametersatz zusammengefügt. Aufgrund der unterschiedlichen Prozessbedingungen, bei denen die jeweiligen Probekörper hergestellt werden, ist dieser Materialparametersatz jedoch inkonsistent und kann nie das Verhalten einer einzelnen Probe beschreiben. Daher wird in der vorliegenden Arbeit ein Messverfahren entwickelt, mit dem es möglich ist, alle relevanten Materialparameter unter besonderer Berücksichtigung von Dämpfung an einem einzelnen Probekörper allein durch Impedanzmessungen zu bestimmen. Als Probekörper wird dazu eine in der Anwendung häufig verwendete Scheibengeometrie verwendet. Um eine hinreichend hohe Sensitivität auf alle Materialparameter zu gewährleisten, wird diese mit einer optimierten Elektrodentopologie gefertigt. Da in diesem Fall keine analytische Betrachtung mehr möglich ist, wird das Messverfahren durch einen inversen Ansatz realisiert. - lang: eng text: Design processes of ultrasonic transducers become increasingly simulation-driven due to rising computational capabilities. Therewithin, the choice of the material parameters for modelling the materials used is particularly important for a realistic simulation result. Piezoceramics, which couple mechanic and electrical properties, are often used as active elements in ultrasonic transducers.The IEEE Standard on Piezoelectricity is a standardised procedure for determining these parameters that requires five impedance measurements on four piezocermics of different geometry. Since only a subset of all necessary material parameters can be determined for each individual specimen, these are then combined to form a complete set of material parameters. Due to different processing conditions for each specimen, this set of material parameters is inconsistent and cannot describe the behaviour of a single specimen appropriately. Therefore, in the present thesis, a method is developed with enables the determination of all relevant material parameters including damping on a single piezocermic by means of electrical impedance measurements alone. A piezoelectric ceramic with disc-shaped geometry, which is frequently used in applications, is used as a specimen.In order to ensure a sufficiently high sensitivity to all material parameters, it is manufactured with an optimised electrode topology. Because in this case analytical solutions, which relate the measurement quantities to the material parameters, do not exist, the measurement method is implemented using an inverse approach. author: - first_name: Nadine full_name: Feldmann, Nadine id: '23082' last_name: Feldmann citation: ama: Feldmann N.   Ein modellbasiertes Messverfahren zur Charakterisierung von Piezokeramiken unter Verwendung eines einzelnen scheibenförmigen Probekörpers.

A newly developed procedure can be used to identify the behaviour of piezoceramic discs over a wide frequency range using a single specimen via fitting simulated and measured impedances by optimising the underlying material parameters. Since there is no generally accepted damping model for piezoelectric ceramics, several mechanical damping models are examined for the material identification. Three models have been chosen and their ability to replicate the measured impedances is evaluated. On the one hand, the common Rayleigh model is considered as a reference. On the other hand, a Zener model and a model using complex constants are extended to model the transversely isotropic material. As the Rayleigh model is only valid for a limited frequency range, it fails to model the broadband behaviour of the material. The model using complex constants leads to the best fit over a wide frequency range while at the same time only adding three additional parameters for modelling damping. Thus, damping can be assumed approximately frequency-independent in piezoceramics. author: - first_name: Nadine full_name: Feldmann, Nadine id: '23082' last_name: Feldmann - first_name: Veronika full_name: Schulze, Veronika last_name: Schulze - first_name: Leander full_name: Claes, Leander id: '11829' last_name: Claes orcid: 0000-0002-4393-268X - first_name: Benjamin full_name: Jurgelucks, Benjamin last_name: Jurgelucks - first_name: Lars full_name: Meihost, Lars id: '24769' last_name: Meihost - first_name: Andrea full_name: Walther, Andrea last_name: Walther - first_name: Bernd full_name: Henning, Bernd id: '213' last_name: Henning citation: ama: 'Feldmann N, Schulze V, Claes L, et al.
