Arup Pedestrian Impactor Models

One of the most challenging areas of vehicle safety engineering is pedestrian safety. Meeting the new and continually improving legislation is a challenging task. This task cannot be undertaken without using the correct tools.

To this end, Arup has developed a family of pedestrian impactor finite element models for use with the LS-DYNA analysis code. This family consists of:

European Headform Models

• EU (ACEA) 3.5kg Child/Small Adult Headform Model
• EU (WG17) 2.5kg Child Headform Model
• EU (WG17) 4.8kg Adult Headform Model

European Legform Models

• EU (WG17) Upper Legform Model
• EU (WG17) Lower Legform Model

Japanese & ISO headform Models

• J-NCAP 3.5kg Child Headform Model
• ISO (J-NCAP) 4.5kg Adult Headform Model

These models have been used successfully in vehicle crash programs by various OEMs worldwide.

Automatic Positioning, Analysis and Post-Processing Using Oasys Software

The headform models can be used in combination with the Oasys Suite of software to automatically set up a series of headform impacts, run the models and post-process the results into a report format.
