The main focus of this paper is the integration of an integrated function modeling (IFM) framework in an engineering framework based on graph-based design languages (GBDLs). Over the last decade, GBDLs have received increasing attention as they offer a promising approach for addressing several important challenges in engineering, such as the freque...

The task of designing and planning an assembly system is complex and challenging. Today, planning results are often dependent on the experience and methodological skills of the planner as well as on the available planning tools available. Digital processes are used to accelerate the planning process and establish the best possible shared knowledge...

The current increase in road traffic in cities requires innovative, low-emission and flexible solutions for passenger transport on short distances. The main topic of this paper is a customer-oriented digital design process of a self-balanced scooter, which can be used as an individual last-mile means of transport between for example public means of...

This paper presents a novel approach to include a holistic description of abstract physics in a digital engineering framework. Physical phenomena realize the numerous functions of technical systems and are an important link between rather abstract product functions and the concrete product geometry and material. Until now, a possibility to integrat...

In a market-driven economy, the availability of an evaluation of the manufacturability cost and economic efficiency right on from the early design phase is a competitive advantage. For this reason, a methodology is proposed in this work which enhances the planning capabilities and efficiency by automatic provision of steel constructions with manufa...

Today manufacturing companies are increasingly using digital tools to react to the increased product complexity. The process today, however, is still characterized by manual activities for changes or missing data continuity, which leads to errors in the digital models for the product and assembly system. Scope of this research is a complete digital...

Graph-based design languages offer a promising approach to address several major issues in engineering, e. g. the laborious manual transfer between CAD and CAE. Such languages generate a digital meta- or system model storing all relevant information about a design and feed this into any relevant CAE tool as needed to simulate and test the impact of...

The paper describes a physics based reconstruction algorithm for the generation of clean, parametric, beam like native CAD structures from density based topology optimization (TO) results. As an algorithmic key element in this process, a physics based stress tensor criteria available from density based TO results is used in the automated TO result...

Graph-based design languages aim at the holistic digital design and representation of complex industrial products. These languages are based on the structure of natural languages, in which the vocabulary and the rules define a language grammar. The translation of the abstract graph-based design language into multiple specific domain-dependent engin...

Today, the product development process is characterized by increasing diversity. A trend towards customer-tailored products can be observed. This trend demands new processes for product development and manufacturing. Increasing product individuality up to lot size one can be faced with methods, which automate the design process and avoid redundant...

For several decades, a wide-spread consensus concerning the enormous importance of an in-depth clarification of the specifications of a product has been observed. A weak clarification of specifications is repeatedly listed as a main cause for the failure of product development projects. Requirements, which can be defined as the purpose, goals, cons...

In recent years the research concerning the representation of product functions has intensified again. Current studies exhibit a growing interest of design engineers to apply such representations in their daily practice. Simultaneously, a growing interest concerning graph-based methods for the digital representation of product models and the pro...

Graphenbasierte Entwurfssprachen sind eine neue Sichtweise auf die ganzheitliche Beschreibung von Produkten, die sich am Aufbau natürlicher Sprachen orientiert, in welcher Vokabeln und Regeln eine Grammatik bilden. In Verbindung mit graphenbasierten Entwurfssprachen steht mittlerweile ein leistungsfähiges Engineering-Framework zur Verfügung, das au...

This paper describes the formal representation approach used in the scope of a large-scale research project aiming at the holistic, completely digital representation and automated computability of the product life-cycle (PLC). The distinctive approach consists in the novel methodology of visual, graph-based design languages expressed in UML (Unifie...
