  1. Vibrational Characteristics of Dummy Headforms

    Dingelstedt, Kristin J.Virginia Tech2024

    The Hybrid III and NOCSAE headforms are two headforms used in impact testing, though their vibrational characteristics are not well understood. They may have different kinematic responses in various impact scenarios if the impact excites any of their natural frequencies; resonance is especially …

  6. Development and Implementation of Laboratory Test Methods for the Evaluation of Wearable Head Impact Sensors

    Tyson, Abigail M.Virginia Tech2016

    … A custom pendulum was used to impact a NOCSAE headform mounted on a Hybrid III neck. Sensors were tested under helmeted and unhelmeted conditions, according to their prescribed use. The headform was impacted at four locations, each at four impact energies ranging from 25 g to 100 g. Peak …

  9. Quantifying the Effect of Helmet Fit on Performance

    Smith, Joseph AdamVirginia Tech2016

    … An impact pendulum was used to strike a helmeted NOCSAE headform mounted on a Hybrid III neck. Helmets were impacted at 4 locations at 3 energies representing a range of concussive to sub-concussive impacts. The fit conditions evaluated in this study represent fitting scenarios in which an athlete …
