The present invention provides a system and a method to enhance HYGE impact simulator sled testing, enabling more accurate measurements of lower leg injury criteria and providing a more accurate restraint system evaluation during a HYGE impact simulator test. The system provides the generation of both rotational and translational footwell intrusion, replicating an actual barrier crash impact test. The rotational and translational footwell intrusion includes foot motion; lower leg motion, including various forces and moments; and knee motion, including interaction with the instrument panel.
