Digital Mock-Up Functional Simulation for Product Conception and Do wnstream Processes

Résultats exploitables

Based on the analysis of user requirements in four different areas of application (dynamics, flexible parts, electro-magnetic compatibility ad aerodynamics), a set of common user requirements was identified. This led to the definition of the integration tools required, the core system, which contains common functionality as: - Data-base. - Visualisation. - Application manager. - Drivers and tool boxes. The Core system and existing simulation tools were used to build demonstrators for different areas of applications. This way the integration of simulation tools could be demonstrated and tested. Most of the concepts and software of this project have been inserted into commercial products that are available. The following software products were involved: - Dassault Systèmes: Catia V5 - LMS: Virtual.lab - Fraunhofer Gesellschaft, Institut für graphische Datenverarbeitung: Visualisation system - University of Parma: PARTICLE - Samtech: BOSS Quattro and SAMCEF/MECANO The benefits of that project are two-fold, depending on the view of the end users and of the IT vendors: The application of the results within user companies, like automotive and aerospace industries, as well as other industries, will achieve dramatic changes in the processes and the benefits from the resulting changes will be: - Dramatic reduction of the development time. - Product quality improvement. - Reduction of redesign costs. The economic benefits will accumulate within the next four to five years to: - Reduction of physical mock-ups: 10%. - Reduction of costs due to late design changes: 10%. - Reduction of scrapping volume: 15%. - Reduction of resources and service tools not necessary: 20%. On the other hand, the IT vendors gained from the user input of new ideas to enhance their existing products or develop new ones. Some parts of the evaluated prototype software are already available in the market. That means that the positions of those companies were already strengthened and will continue to be in the future. A preliminary version of the Project web site ( has been realised.
