Knowledge-Based Design

The chapter “Knowledge-Based Design”, covers the use of template models, integrated calculation and simulation procedures, and automated routines to support product design. Knowledge-based design enables the collection, storage and re-use of expert knowledge, as well as the subsequent integration of know-how into development processes. Using examples from component and assembly development, the chapter elaborates on the potential of enhanced parametric-associative design and knowledge-based engineering used in combination with simultaneously linked calculation procedures.

Modeling Techniques in CAD

The chapter “Modeling Techniques in CAD”, includes a detailed introduction of design methods within the CAD environment. Structures and strategies of wireframe, surface and solid modeling are presented and discussed in terms of their application in collaborative product development processes. Beyond the application of primary CAD functionalities, this chapter uses specific examples from the automotive industry to present a variety of methods for the efficient creation of mechanical components and assemblies.

Overview of Virtual Product Development

The chapter “Overview of Virtual Product Development”, first provides a summary of the various stages in the life cycle of mechanical products. The main terms, definitions, and methods of computer-aided product development are then introduced. This includes the historical development of computer-aided design, simulation, and data management. In addition, some selected, representative development workflows in automotive engineering are presented and discussed, and the chapter then closes with a brief introduction to the concepts of collaborative product development.

Engineering Data Management

The chapter “Engineering Data Management” (EDM), describes the fundamental principles of this approach, which involves the interdepartmental and interdisciplinary integration of data and workflows in automotive product development. Both complete EDM use cases and the basic functional modules of CAD and computer-aided engineering (CAE) are described in the context of process-oriented product life cycle management approaches. Finally, the chapter also presents the system-oriented view by describing EDM system architecture with integrated computer-aided applications and data management systems.

Automotive Development Processes

The chapter “Automotive Development Processes”, includes a retrospect of achievements in the automotive industry and highlights the very different factors that have influenced the development of cars over the last 120 years. The wide range of requirements for current and future cars is then elaborated, in order to clarify the current challenges facing automotive development. In addition, the stages in automobile development are explained through a detailed analysis of the different project phases, including a discussion on the integration of virtual product creation throughout the entire development chain.

Knowledge Management in Product Development

The chapter “Knowledge Management in Product Development”, describes product knowledge as a basis for investigation, as well as the development of such knowledge across the product life cycle. The chapter introduces and discusses the fundamentals of knowledge, knowledge management and knowledge transfer, as well as the principle related basic models and approaches. Thus, the chapter offers a summary of current scientific findings in the area of knowledge management that serves as background for further analysis.

Advanced Applications of CAD/EDM in the Automotive Industry

The chapter “Advanced Applications of CAD/EDM in the Automotive Industry”, offers a selection of concrete use cases in automotive development. One use case includes an application of knowledge-based EDM, which highlights the importance of the interaction of knowledge processes and data management throughout virtual product development. This use case also describes the integrated application of computer-aided design, simulation and management throughout the daily operations of development processes. Another use case describes the integration of CAD data management in automotive engineering, which is an essential topic in the area of engineering data management. Finally, a use case describing an approach of a parametric-associative concept model for initial vehicle development highlights the various working fields involved in automotive concept phases and introduces a model for geometrical and functional integration.
