The dynamic behavior of structural components is significantly influenced by the environmental temperature. The vibration behaviour changes with varying temperature due to changes in stiffness and damping, as well as influences in the boundary conditions and geometry. This effect is particularly noticeable in FRP structures. To accurately determine these effects on the dynamic behavior of structures, detailed material testing and simulation-based analyses are required, with temperature-dependent material parameters posing a major challenge. In this paper, a holistic approach to vibration characterization of large components is developed. With the help of experimental resonance tests on a simplified structural level and the transfer of the measurement results by inverse parameter identification, an approach is provided to estimate the vibration behavior of large structural components. A part of the primary structure of an aircraft is used as a case study for the procedure and the resonance tests on an electrodynamic shaker. © 2024 Proceedings of ISMA 2024 - International Conference on Noise and Vibration engineering and USD 2024 - International Conference on Uncertainty in Structural Dynamics.

Additive manufacturing produces 3D geometries by depositing material in a layer-by-layer fashion. Commonly, the resolution of additive manufacturing is in the millimeter and micrometer scales, due to limitations in mechanical precision and material properties. In the past two decades, nanoscale additive manufacturing has been achieved using femtosecond lasers that crosslink resin through a two-photon polymerization lithography (TPL) process. In this progress report, we present some of the recent efforts on nanoscale printing using TPL. We provide examples of nanoscale 2.5D, 3D and 4D printing by TPL and their corresponding applications in nanophotonics. We discuss the benefits of fabricating these geometries by the printing approach. Finally, we summarize the challenges and provide our perspective to improve the performance of nanoscale printing. © 2022

product systems no longer consist merely of discrete components that can be designed and developed independently. Instead, the product systems take on an increasingly complex shape, reflected in product architecture development. Various stakeholders in this product architecture must collaborate across life phases and disciplines to an increasing extent. To support the exchange in multi-disciplinary product systems in the context of modularization, the visualization tool of the "Module Harmonization Chart (MHC)" is presented in this paper. The "MHC" enables the representation of components in a multi-disciplinary system, thus supporting cross-disciplinary collaboration in developing an integrated modular design. Aspects such as discipline-specific module drivers and targeted sub-system segments can be used to address a holistic module design and improve overall system integration. © 2023 The Authors.

The concept of a virtual representation of a physical asset can be traced back to the sixties and is currently widely found under the term Digital Twin. Today, increasingly more implementations of this concept in a variety of applications occur, each with individual boundary conditions and views. Aviation and, especially its retrofit, face the need for such representations but also, its very own circumstances. After giving a brief introduction to the world of aviation, its cabin-retrofit and the need for a good virtual representation of aircraft, the history of the concept of Digital Twins is presented. A literature study results in an overview of current definitions, and research domains but also occurring challenges. The results are contrasted with the perspective of aviation's cabin-retrofit and an assessment of the definitions and terminology is given. © 2023 The Authors. Published by Elsevier B.V.

A company's business model focuses on delivering personalized products or changing its offering to a product-Service System impacts the underlying product architecture. Depending on the aim, different product architectures need to be designed. Therefore, modularization utilizing module drivers offers the advantage that additional objectives can be addressed. This contribution identifies module drivers focusing on the architecture design of personalization, collaboration, or PSS, which are not yet known. Analyzing existing literature and empirical findings, dependencies between different module drivers and product architectures are identified. As a result of this contribution, an extended view of module drivers in various product architecture applications is given. © 2022 die Autoren.

This paper addresses the question of how Modular design methods can support the development of complex products. The goal of selected Modular design methods is to improve transparency in the development of modular systems to be able to structure these systems in a way that adds value to the observed company and to derive optimized product architectures from the conducted procedures. The problem addressed here is that existing methods can develop increasingly less transparency within the development of complex products, since the extent of these products rises increasingly. This increases the complexity of the work steps and scope of work, which results in a reduction of the immediate transparency in observing the underlying product architecture. To address this pain points, two selected methods in the context of Modular design are exemplary adapted to agile approaches and principles. These adaptations are applied to two underlying case studies, each of which has to do with the development of complex products in various aspects. In the case studies, different process perspectives are depicted, which offer both a development process (further development of an existing system) of a laser cutting machine tool of a mechanical engineering company, as well as a development project (new design of a system with a high degree of novel development) of a smart industrial valve of a medium-sized engineering manufacturer with, in addition, an unknown proportion of new development as an investigation environment. The results show the integration of agile aspects in selected Modular design methods as a successful support in generating transparency in the development of complex products and systems, in different process perspectives. At the same time, the research also shows that adaptations to the studied methods are necessary, such as continuous and centralized concept documentation, to apply them in an agile context. © Proceedings of Norddesign 2022: How product and Manufacturing

This bibliometric analysis identifies the extent to which the methodical development of modular product families (product side) and agile project development (process side) can be beneficial for coping with complex product development tasks. The accomplished co-occurrence analysis reveals an indirect relationship between the development of modular product families and agile product development. This indirect connection is because the different methods are incorporated in the field of design Methodology. However, the analysis leaves a gap in the direct interaction of both subjects, a subsequently accomplished bibliographic coupling points out. A consecutive in-depth abstract and paper analysis reveals further research on their integration is necessary. © 2023 IEEE.

Honeycomb sandwich structures are widely used for cabin interior components in passenger aircrafts. The load introduction into the sandwich structure proves to be particularly critical. However, the verification takes place based on non-standardized tests abstracted from the application so that influences caused by boundary conditions and multiple load introduction points cannot be investigated. Moreover, these tests also do not allow comparisons of different designs. The variety of different test setups on component level has made the comparability of published results more difficult. This paper summarizes the state of the art of existing component tests. Based on that and using the example of an aircraft cabin partition, the existing test setups are checked for their suitability to cover all given load cases. New test setups with extended boundary conditions and several load introduction points are developed. For one test setup, test results are shown and compared to a conventional component test. ©2022 Hartwich et al.

This work introduces version 2.0 of the Hamburg ANatomical NEurointerventional Simulator (HANNES): a novel modular neurointerventional simulator designed to provide a realistic platform for simulating various neurovascular pathologies and their endovascular therapies. Collaboratively developed by physicians and engineers, the neurointerventional simulator is designed with a modular product architecture combining standardized and variant modules to represent different training scenarios. The additively manufactured patient-based and patient-specific blood vessel tree consists of up to 13 individual components, including standardized features and interfaces for ease of connection. Patient-specific vessel models derived from medical imaging data allow customization and complexity adjustment. HANNES supports diverse neurointerventional training scenarios, including various modalities of aneurysm embolization, internal carotid artery (ICA)-stenosis, and thrombotic vessel occlusions, which can be treated through a transradial or transfemoral approach. The use and benefits of the model were evaluated with a group of trainees, who provided positive feedback, confirming the model's practicality and effectiveness in enhancing neurointerventional technical skills. In conclusion, HANNES represents a significant advancement in neurointerventional training, addressing the limitations of traditional training methods by simulating diverse disease patterns, enhancing medical staff's skills, and facilitating product testing. © 2025 by ASME.

Machine learning (ML)-based surrogate models offer a promising alternative for Multibody Dynamics (MBD) Simulation of railway vehicle-track dynamics systems. A well-built ML model can accurately and quickly predict the dynamic responses to various track irregularities, significantly reducing computation time and unifying integration interfaces of different vehicle-track systems. However, training effective surrogate models is a complex process, influenced by the specific needs of the analysis. Different algorithms and training sets might be required for different surrogate models, making it essential to research the impact factors for building these models. This paper presents a comparative analysis of ML-based surrogate modeling approaches tailored for MBD Model within a railway digital twin platform. The primary focus is evaluating the performance of various ML-based surrogate modeling approaches, as well as the influence of neural networks, training parameters, and data sources. By leveraging extensive simulation and measurement data, we assess the ability of these surrogate models to predict key performance indicators under varying operational conditions. This analysis provides valuable insights for railway engineers in selecting appropriate surrogate modeling approaches, ultimately contributing to the advancement of predictive maintenance and optimization in railway operations. © 2024 IEEE.
