CURRENT & FUTURE TECHNOLOGIES IN AUTOMOTIVE ENGINEERING SIMULATION
Some of the digital models have completely different aims and require
completely different input data. Others might be more similar and there
might be a chance to combine or to merge them even. This of course would
save maintenance costs and could help to streamline processes in a
concurrent engineering environment. A careful selection of appropriate
software tools would be required in that respect as well as a close working
relationship with ISVs (Independent Software Vendors).
4.5.2 Becoming Faster in the Conceptual Design Phase
In the different design phases, digital models must conform and correspond
with each other so that results support significantly reliable decision-making
and progression through all stages. This means that at one design stage it
would be appropriate to rely on qualitative decisions (e.g. version A is better
than version B), whereas at another design stage quantitative simulation
results are crucial for final verification and validation.
To ensure this conformity, it is becoming clear that CAE needs to take
advantage of the existing PLM / PDM systems that can provide the tracking,
access control and alignment of the various models and phases of the
design, and link them to the main product structure (BOM = Bill Of
Materials).
The SDM systems need to provide repeatable automation solutions
(templates) that are open to any CAE application to open up the world of
Multi - Disciplinary automation and Optimization (= MDO).
Therefore, we propose that CAE methods be applied Up-Front, either to do
earlier and faster analysis runs or to leverage knowledge from previous
designs, such as by means of Simulation Data and Process Management
(e.g. Ref. [12]). Disciplines currently handled by SDM include: Front, Rear,
and Side Crash; Pedestrian Protection; Occupant Safety; Head Impact;
Global and Local Stiffness, and NVH Analysis. In addition, these different
simulation disciplines have to be linked for collaborative working in order to
fully support the conceptual design phase with an appropriate visualisation
environment such as a VR system which already has shown its benefits in
fields like packaging or ergonomics (e.g. Ref. [12]).
