SAE International Compliant Parts Simulation Procedure 2012-01-0948

The development of virtual techniques becomes more and more important for the automotive industry to allow an acceleration of the vehicle development and the reduction of hardware prototypes. By analyzing the main problem points arising on the first hardware builds it came out, that compliant parts are most critical, since their digital representation does not coincide with the reality, so that many changes are made after first hardware validation. Already some years ago GM has started to work together with the Fraunhofer-Chalmers Centre in Gothenburg, Sweden, on the development of the software Industrial Path Solutions (IPS) . At one side the enhancements of the software itself build up the basis for investigations of cables, hoses etc, at the other side in particular for this kind of simulation the industry itself has to invest a lot effort for the effective application of the software. To allow the effective usage of compliant part software load cases were defined. These had been classified regarding their requirements on the software and thus a status had been determined for each class, which indicates the feasibility. On the basis of issues with compliant parts the above procedure will be explained and demonstrated to show the benefit of such software for the automotive industry.
