Computer-Aided Engineering Environment for Designing Tailored Forming Components

Abstract

The use of multi-material forming components makes it possible to produce components adapted to the respective requirements, which have advantages over mono-material components. The necessary consideration of an additional material increases the possible degrees of freedom in product and manufacturing process development. As a result, development becomes more complex and special expert knowledge is required. To counteract this, computer-aided engineering environments with knowledge-based tools are increasingly used. This article describes a computer-aided engineering environment (CAEE) that can be used to design hybrid forming components that are produced by tailored forming, a process chain developed in the Collaborative Research Center (CRC) 1153. The CAEE consists of a knowledge base, in which the knowledge necessary for the design of tailored forming parts, including manufacturer restrictions, is stored and made available. For the generation of rough and detailed design and for elaboration the following methods are used. The topology optimization method, Interfacial Zone Evolutionary Optimization (IZEO), which determines the material distribution. The design of optimized joining zone geometries, by robust design. The elaboration of the components by means of highly flexible computer-aided design (CAD) models, which are built according to the generative parametric design approach (GPDA).

Functional Requirements and Design Features for the Implementation of 3D CAD-Based Graphical Interactive Configurators

“…In algorithmic modeling, the focus is on automating the design process rather than pre-formulated solutions [4,23]. Algorithms are used to extract product properties from requirements and build product design rules, also taking into account external data or numerical simulations [24][25][26]. Therefore, a parametric product master model is unnecessary, as this approach aims to generate an individual product for each set of customer requirements.…”

Process Chain-Oriented Design Evaluation of Multi-Material Components by Knowledge-Based Engineering

“…Therefore, in addition to empirical investigations, research is increasingly using validated simulation models to develop knowledge about the tailored forming process chain. This knowledge is fed back into product development in the form of knowledge-based methods and tools to support the manufacturing-oriented design of tailored forming components and to make the complex technology applicable for design engineers [18].…”

Making design decisions under uncertainties: probabilistic reasoning and robust product design

“…Another way of implicitly considering data and context uncertainties is the creation of design automation systems. Here, the design process of a component is completely formalized and implemented into a computer aided engineering environment (Brockmöller et al, 2020;Amadori et al, 2012;La Rocca & van Tooren, 2010). Variations of requirements can be directly computed into product variants, allowing to analyze sensitivities of changes and find clusters of solutions for requirement sets (Siqueira et al, 2019;Schätz et al, 2010).…”
