Development of a test method for evaluating safety helmets' ability to reduce skull fracture and brain injury risk from falls in construction
… brain injuries (TBIs), however current safety helmet standards do not test safety helmets under impact conditions realistic to this injury event. Safety helmets are broadly classified into two groups: Type I, which are tested at the top of the helmet and Type II, which are tested to the top and …

Accelerated computational modeling of ballistic helmet test protocols
In modern combat, helmets play a vital role in protecting the head. Before being delivered to the soldier, combat helmets undergo a series of tests to determine their threat mitigation performance. During ballistic testing, current combat helmet test protocols use clay to record the helmet backface …

Head Impact Conditions and Helmet Performance in Snowsports
… rotational kinematics of head impact. Currently helmet testing standards don't consider these rotational kinematics, or varying friction conditions that potentially occur in real-world scenarios. The purpose of this study is to investigate the head impact conditions in a snowsport environment to …

Laboratory and Field Studies in Sports-Related Brain Injury
… exposure in youth football was observed using a helmet mounted accelerometer system to measure head kinematics. The results suggest that restriction on contact in practice at the youth level can translate into reduced head impact exposure over the course of a season. A second study investigated …

Occupational Head Protection: Considerations for Test Methods and Use
… in this thesis raises considerations for future helmet testing protocols in order to better match real-world simulations.

Physical Testing of Potential Football Helmet Design Enhancements
… about the design. In order to fully test the helmet design; however, full scale testing was required. In order to carry out this testing a drop tower was built based on National Operating Committee on Standards for Athletic Equipment, NOCSAE, specification. The drop tower designed for Cal Poly …
