CONCLUSION

Conclusion

► New dummy’s are being specified in new procedures requiring new models

– New models are being developed: Q6, Q10, WorldSID50, WorldSID5, FLEX PLI GTR

► Existing dummy models see further improvements – Up-to-date to the latest dummy hardware

– Up-to-date to the latest solver code

– Improved predictions

– Outlook: Harmonization → Next step to reach more reliable CAE predictions

Humanetics RADIOSS Models are developed in co-operation with Altair
