Article
Co-simulation is a prominent method to solve multi-physics problems. Multi-physics simulations using a co-simulation approach have an intrinsic advantage. They allow well-established and specialized simulation tools for different fields and signals to be combined and reused with minor adaptations in contrast to the monolithic approach. However, the...
Thesis
Full-text available
Co-simulation is becoming an increasingly integral and indispensable technique for solving today’s challenging engineering problems. By means of this code coupling technique, the engineering problem is partitioned as an assembly of different subsystems exchanging solution information at run time. The inherent advantage of co-simulation in contrast...

The vibroacoustic assessment and optimization of vehicle components at the early stage of complete vehicle development is an essential. This is because only at the early phase it is possible to change concepts. Therefore, it is necessary to focus on analysis methods which can work with a limited set of information in contrast to the high-fidelity m...
Article
The evaluation of energetic quantities by means of structure-borne sound power is an attractive approach in analyzing coupled vibroacoustic systems and material characterization. When cyclic mean power quantities are determined for non-resonant frequencies of a system, the accuracy of the relative phases between force and acceleration signals can b...
Chapter
The paper presents a practical approach to deploy Krylov-based model order reduction techniques for industrial vibroacoustic problems. The numerical analysis of frequency-domain transfer functions provides valuable insights into the model’s behavior even at an early stage of product development. Model order reduction is a promising approach to yiel...
Chapter
A parametric model order reduction approach for the frequency-domain analysis of complex industry models is presented. Linear time-invariant subsystem models are reduced for the use in domain integration approaches in the context of structural dynamics. These subsystems have a moderate number of resonances in the considered frequency band but a hig...
Research
A two-dimensional finite element (FE) model is presented, which can be used to verify methods and design criterions for vibroacoustics. A simple beam-like structure, providing different transmission paths for some structure-borne point excitation, is connected to a beam. The latter is acting as a radiator. The acoustic fluid is modeled by means of...
Conference Paper
The evaluation of structure-borne sound power is an effective analysis tool for the analysis of the structure-borne sound transmission in mechanical structures like vehicles, but also for the characterization of components. However in the case of measurement-based methods in particular the phase-accuracy becomes challenging for lightly damped syste...
Article
Full-text available
The vibroacoustic assessment and optimization of vehicle components at the early stage of complete vehicle development is an essential competitive factor. For the low and mid-frequency range mainly transfer functions are used, which are formulated in primary variables like forces or displacements. This approach, however, considers only a part of th...

This paper investigates data mapping between non-matching meshes and geometries in fluid-structure interaction. Mapping algorithms for surface meshes including nearest element interpolation, the standard mortar method and the dual mortar method are studied and comparatively assessed. The inconsistency problem of mortar methods at curved edges of fl...

Objectives: The objective of the present paper is to provide a challenging and well-defined validation test case for fluid-structure interaction (FSI) in turbulent flow to close a gap in the literature. The following list of requirements are taken into account during the definition and setup phase. First, the test case should be geometrically simpl...
Conference Paper
Dieser Beitrag diskutiert die Potenziale des Einsatzes von modernen numerischen Berechnungsverfahren im Windingenieurwesen und die Bedeutung von windspezifischen Modellierungsaspekten. Anhand von praxisnahen Beispielen werden die physikalische Aussagekraft der Simulationen und die notwendige Validierung aufgezeigt

Most technical products are an assembly of different systems. In product design, simulation is a well established tool in order to accelerate the development-to-market time. For a lot of physical phenomena sophisticated simulation tools exist, e.g. for fluids Computational Fluid Dynamics (CFD) or for structures Computational Solid Mechanics (CSM)....

Fluid-structure interaction (FSI) is a topic of major interest in many engineering fields. The significant growth of the computational capabilities allows solving more complex coupled problems, whereby the physical models get closer to reality. The long-term objective of the present research project is to simulate practically relevant light-weight structural systems in turbulent flows. For this purpose, a cooperation between the Helmut-Schmidt University Hamburg and the University of Technology Munich was established. Project financed by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) under the contract numbers BR 1847/12-1, BR 1847/12-2, BL 306/26-1 and BL 306/26-2.
