  7. Grid Challengesin Automotive Industry The challenge of integrating • different disciplines: • Design (CAD) • Simulation (CAE) • Test (CAT) • different locations • different organisations

  8. Product Structure- Simulation Structure CAD – CAE Integration Situation: For build-up of a simulation model • structural information • geometric and • material data from CAD are needed • Structure differs from load case to load case • Geometric representation of the parts differs from load case to load case Only the CAE engineer knows,which part is used and in which form it is represented

  10. Product Structure- Simulation Structure Selection of detected rules: • Structure parts are parts with the middle group number801-806, 807-810, 813, 814, 817 • Structure parts were modelled physically (mesh) • Structure parts go into the include body • … Status: • CAD-CAE mapping of more than 80% of a car with 1500 parts for NVH trimmed body • prototype with ontobroker realised • 35 rules only from structural information • in progress – search for more rules using more attributes

  18. HeterogeneousData Structures Audi use case forCAE/CAT integration: • View and use CAT data inthe same manner as CAE data in the CAE data management system A3 (1354) A4 (356) A5 (170) A6 (107) A8 (325) TT (211) A3 (54) A4 (56) A5 (70) A6 (107) A8 (35) TT (27) Q7 (21) Convertible Coupe

  19. HeterogeneousData Structures CAT (Test) • Vehicle configuration • Test case • Measured results • Sensor output files • Channels • Movies • Measured Values • Evaluation of measured results • Curves • Images • Values CAE (Simulation) • Input Deck • Model • Design variant • Load case • Results • Output files • Post Process Objects • Curves • Animations • Pictures • Values • Cross sequences

  20. HeterogeneousData Structures CAE System CAT System • CAE System formulates request according to own data model • Request is transformed into data model of the CAT system • CAT System answers request. The answer is transformed again and sent back
