Abstract

This paper provides a methodology for adjustment of off-speed head impact test data to the required 24.14 km/h for interior head impact. The "Normalisation Process" utilises the Generic Waveform Concept for its basic foundation. Predicted results from FE Head Impact Simulation Model were used to validate the Normalisation Process. It is recommended that Normalisation should be applied to cases where impact velocities are within plus or minus 0.8 km/h speed difference. In general, Normalising downspeed (from 24.94 to 24.14 km/h). One must always check for potentially severe "bottom-out" condition by examining the pulse shape for any abrupt peaks in headform deceleration. The Normalising Process should not be applied to "glancing" impacts in which the impact and rebound vectors are not collinear. (A)
