Item type:Publication, Access status: without files , A simulation-based approach for the automated design of fatigue resistant continuous fibre-reinforced componentsFibre-reinforced plastics are increasingly being used in important structural components. Here they are often subjected to cyclic loading, which leads to a deterioration in material properties. However current design methods hardly take this fatigue behavior into account. Instead, they rely on conservative safety factors, resulting in over-dimensioned components. In order to realise the full lightweight potential, we propose an innovative method that enables a targeted design for a defined service life. It integrates knowledge from experimental fatigue testing and uses modified mathematical failure criteria to predict the degree of fatigue throughout the part. This allows us to adaptively reinforce fatigue critical areas, resulting in lightweight and fatigue resistant structures.Publicationtype: Conference Paper23 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: with files , Exploratory study to investigate the influence of reference systems in the model of product generation engineeringProducts are developed in generations and based on reference products. The decision and selection of suitable reference system elements (RSE) is a challenging process. In order to investigate the influence of different RSE, human behavior in relation to decision-making must also be considered. The present work is based on the evaluation of extensive work in the field of behavioral economics. The experiments show the influence of reference products on decision-making and development success through the selection of RSE. By classifying and quantifying the products, a correlation between the new development shares of the new product generation and the quality and improvement potential of the reference products is recognized.Publicationtype: Conference Paper114 120 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Product production ecosystems for the reuse of modules in the extended product life cycle(The Design Society, 2024); ; ; ; This paper examines the circularity of products across different product types. The focus is on short circulation paths such as remanufacturing and refurbishing, which offer the greatest value retention. To achieve this, products must have a modular design so that modules can be easily dismantled and reused via standardized interfaces. Sensors are required to record service life-relevant influences and digital module twins to store this data. Other topics include the requirements for modular products for efficient, highly automated disassembly and reassembly as well as the automated configuration of new products from modules with a defined remaining service life.Publicationtype: Conference Paper52 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Lightweight design and variety: A multi-model optimization approach in product developmentThe contribution addresses the integration of lightweight design principles into the product development process while managing the challenges posed by increasing product variety. The paper highlights the conflict between the necessity for weight optimization and the proliferation of product variants driven by market trends. It proposes using multi-model optimization (MMO) to resolve this conflict. By implementing MMO, weight reduction can be achieved in components and modules, before and after the modularization process. The paper details how MMO can be applied at different stages of product development. This approach supports economic constraints and improves the overall product structure through iterative optimization of interfaces and modules.Publicationtype: Conference Paper15
