Helmet impact protection effectiveness rating

Real-world crash data studied.

Hiper test methods are developed based on real-world data. These include more than 1,200 impacts examined in published studies to determine the most frequent helmet impact locations.

State-of-the-art key impact simulations.

Impacts are simulated on a helmet test rig developed at Imperial College. It tests helmets under oblique impacts that are often seen in real-world data, which produce larger head rotation. It uses a state-of-the-art headform for more accurate and precise helmet testing results.

Analysis

Impact results to analyse simulated consequences.

To establish helmet safety performance, the head kinematics results are carefully reviewed and used to estimate the risk of brain injuries associated with the direct forces (linear risk), those associated with the rotational motion of the head (rotational risk) and the total risk.
