Evaluation of the Effects of Swedish Flight Helmets on Manikin Response During+Gz Impact Accelerations

摘要

Swedish helmets 113-B and 116 were fitted to a large Advanced DynamicAnthropomorphic Manikin (ADAM) and subjected to impacts of 8, 10, 15, and 20 G in the +z axis on the Armstrong Laboratory vertical deceleration tower, with neck loading data recorded. Laboratory tests were also performed in order to determine the mass properties of the helmets. The data were analyzed in order to determine the structural integrity and loading effects of the helmets, and the results compared to similar data obtained from tests with USAF HGU-26/P and HGU-55/P helmets. The results indicated that the two Swedish helmets generated significantly less neck compression loading than the two USAF helmets with respect to their relative weights. In addition, the HGU-26/P generated greater neck shear loading than the other three helmets. Variations in the centers of gravity of the helmets as well as the tighter fit of the Swedish helmets could have contributed to the differences among the helmets. 113-B Helmet, Large ADAM Manikin, Neck Shear Force, 116 Helmet, Neck Compression Force, Mass Properties.
