Arup Pedestrian Impactor Models
Pedestrian safety remains one of the most rapidly evolving parts of automotive legislation, and as car design trends shift, engineers need the right pedestrian simulation tools for the job.
European Legforms – Lower Legform
The legform impactor conforms to that specified in UNECE/TRANS/WP.29/GRSP/2013/26, Annex 4.
Validation
This legform model has been validated against the WG17 static and dynamic calibration test, the TRL proposed leaf spring test and to a multiple bumper impact test.
The target speed and mass of the supplied lower legform model is set up in accordance to the Euro NCAP regulation (ref. “Euro-NCAP Pedestrian Testing Protocol v8.4”. November 2017).
Validation work has been carried out in both SMP and MPP versions of LS-DYNA R9.2 and R7.12 to ensure the performance and accuracy.
