BAVARIAN RESEARCH ASSOCIATION FOR CUSTOMIZED DIGITAL ENGINEERING FOR BAVARIAN SMES USING THE EXAMPLE OF THE DRIVE TRAIN OF BATTERY ELECTRIC VEHICLES
Working Group Tools
The working group Tools is concerned with the development and provision of calculation tools for the design processes in the electric powertrain. In cooperation with the participating companies and partners of the network, the individual requirements in the calculation and simulation are first recorded and problem-specific solution concepts in the form of software demonstrators are developed.
The participating subprojects SP 2, SP 4, SP 5 and SP 6 work together on a strategy for identifying the required calculation tools and their implementation as digital tools in the design process. The industrial partners support this by providing practical use cases in the environment of the BEV demonstrator.
In SP 5 analytical calculation tools for the design of machine systems and their components will be developed. Methods of statistical experimental design support a systematic approach to the design of machine systems. At system level, methods are provided to avoid logic errors in the design and thus ensure an inherent control of the development process. The focus of the results is on revealing open potentials and identifying critical system components. Finally, the developed software demonstrators will be provided in the form of a toolbox.
The SP 6 plans to develop virtual sensors for use in the electric powertrain. With the help of the finite element method, these sensors should enable the determination of relevant measurement variables such as structural deformations, system displacements and temperatures at inaccessible points in the test bench. After the identification of the system components to be mapped on the demonstrator, suitable modelling strategies for the underlying FE calculations will be derived. In the context of digital engineering, the calculation results can also be used as input data sets for the machine learning algorithms in SP 1.
The aim of the participants of the working group Tools is also to ensure the transferability of the developed calculation methods and tools to similar problems beyond the demonstrator. At this point, the cooperation partners can also provide use cases outside of the demonstrator.
