Abstract [en]

Technology and engineering might be characterized as becoming more knowledge-intensive. A huge amount of data is used and produced in most product development projects. Increasing competition requires shorter reaction time to customer demands and a higher level of innovation. Concurrent Engineering (CE) is a strategic response to competition. It has proved to be a powerful approach to integrating engineering activities in product development. However, integration and parallel activities, that  is the essence of CE, add complexity to the process. Consequently, information management is recognized as a major component in many CE models. Product Data Management (PDM) systems are a class of computer based systems that address the need to manage product related information that is mainly formal and computer interpretable. PDM systems are sometimes referred to as CE enablers. Results from a recent survey of PDM implementation projects in six Swedish industrial companies, with products ranging from telecommunications systems to trucks and medical equipment, indicate the importance of also utilizing the Concurrent Engineering (CE) approach in the process of implementing an enterprise-wide PDM solution.

Abstract [en]

Efficiency and innovative problem solving are contradictory requirements for productdevelopment (PD), and both requirements must be satisfied in companies that strive to remainor to become competitive. Efficiency is strongly related to ”doing things right”, whereasinnovative problem solving and creativity is focused on ”doing the right things”.Engineering design, which is a sub-process within PD, can be viewed as problem solving or adecision-making process. New technologies in computer science and new software tools openthe way to new approaches for the solution of mechanical problems. Product datamanagement (PDM) technology and tools can enable concurrent engineering (CE) bymanaging the formal product data, the relations between the individual data objects, and theirrelation to the PD process. Many engineering activities deal with the relation betweenbehavior and shape. Modern CAD systems are highly productive tools for conceptembodiment and detailing. The finite element (FE) method is a general tool used to study thephysical behavior of objects with arbitrary shapes. Since a modern CAD technology enablesdesign modification and change, it can support the innovative dimension of engineering aswell as the verification of physical properties and behavior. Concepts and detailed solutionshave traditionally been evaluated and verified with physical testing. Numerical modeling andsimulation is in many cases a far more time efficient method than testing to verify theproperties of an artifact. Numerical modeling can also support the innovative dimension ofproblem solving by enabling parameter studies and observations of real and syntheticbehavior. Simulation-driven design is defined as a design process where decisions related tothe behavior and performance of the artifact are significantly supported by computer-basedproduct modeling and simulation.A framework for product modeling, that is based on a modern CAD system with fullyintegrated FE modeling and simulation functionality provides the engineer with tools capableof supporting a number of engineering steps in all life-cycle phases of a product. Such aconceptual framework, that is based on a moderately coupled approach to integratecommercial PDM, CAD, and FE software, is presented. An object model and a supportingmodular modeling methodology are also presented. Two industrial cases are used to illustratethe possibilities and some of the opportunities given by simulation-driven design with thepresented methodology and framework.
