Project content
Consisting of 26 funded and 2 associated partners from industry and science, the DigiTain research project started on 01.01.2023 with a total project duration of 36 months.
Ecologically and economically sustainable criteria in vehicle and drive architecture development are becoming increasingly relevant in politics, society and industry. The technical and economic criteria of classic product development and optimization with an ecological product assessment only in the late phase of product development are therefore no longer sufficient and up-to-date.
Sustainability assessment during the product development process currently poses major challenges for developers, as suitable digital processes, methods and tools for ecological optimization of the entire vehicle, including the drive components, are not available. In addition, there are no binding standards for fully digital product development and evaluation, which is why a large number of experimental validation tests are still required for certification.
DigiTain is therefore developing precisely those processes, methods and models for the fully digital product development and certification of electric drive architectures that not only aim to develop competitive drives from the outset, but also incorporate ecological and economic sustainability criteria. The aim is to achieve holistic overall vehicle and drive architecture development, taking into account all product property-induced areas. The application and validation of the sustainability-oriented development process (NEP) as well as the developed generic methods and models is carried out using the example of the development and optimization of an electric vehicle with a hybrid drive strategy consisting of a fuel cell unit and HV battery system.
The Chair of Virtual Product Development is working closely with the ILK in work packages 1 and 2 of the DigiTain research project. In WP1, a sustainability-oriented product development process (SDP) is being developed. The aim is to optimize the life cycle assessment at component and overall vehicle level during the product development process. In WP2, the documentation and traceability of calculation process chains for a more predictive CAE modeling and validation of vehicle components is considered. The focus here is on recording the relevant intermediate results and optimization steps in PDM/PLM systems. The Dresden project partner XPLM Solution GmbH is involved in the project with the necessary program implementation and integration of new interfaces.
