A Laboratory Study on the Effect of Helmet Fit on Biomechanical Measures of Head and Neck Injury in Simulated Impact
DownloadFall 2017
Conventional wisdom and the language in international helmet testing and certification standards suggest that appropriate helmet fit and retention during an impact are important factors in protecting the helmet wearer from impact-induced injury. This thesis aims to investigate impact-induced...

An impact force transducer for anthropomorphic test dummy headforms: Application to study effects of external helmet accessories on biomechanical measures of head injury risk
DownloadFall 2015
The first half of this thesis describes the mechanical design, calibration and validation of an in-fibre Bragg grating based impact transducer. The transducer comprises an in-fibre Bragg grating fixed to an aluminum superstructure (12 mm in diameter, 3 mm thickness) designed to withstand typical...
