Experimental Modal Analysis of the Advanced Combat Helmet
In this work we present a study of the characterization of an Advanced Combat Helmet (ACH) using experimental modal analysis techniques. A medium-sized helmet was impacted at different location and the vibration response was used to estimate a global frequency model. This was achieved using the modal parameters of the local models obtained for a specific input-output location and combining them...
متن کاملHow satisfied are soldiers with their ballistic helmets? A comparison of soldiers' opinions about the advanced combat helmet and the personal armor system for ground troops helmet.
Many factors are considered during ballistic helmet design, including comfort, weight, fit, and maintainability. These factors affect soldiers' decisions about helmet use; therefore, rigorous research about soldiers' real-life experiences with helmets is critical to assessing a helmet's overall protective efficacy. This study compared soldiers' satisfaction and problem experience with the advan...
متن کاملInjuries of the head from backface deformation of ballistic protective helmets under ballistic impact.
Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed "behind armor blunt trauma" (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize th...
متن کاملJoint Design for Advance Ceramic Armor under Ballistic Impact
The objective of this research is to develop a new methodology with software tools for the joint design of an advanced composite armor (ACA) under ballistic impact and other loading conditions. An innovative design methodology, topology optimization, is extended for the composite armor joint design problem. This includes ballistic impact analyses of the ACA, function analyses and targets settin...
متن کاملFinite element modeling of the human head under baton impact
Purpose: This research will try to predict damage probability and calculate the main stress resulted from baton impacts by finite element (FE) modeling of the human head considering skull texture, brain and cerebrospinal fluid.Materials and Methods: A three dimensional FE model of the skull-brain complex was constructed for simulating the baton impact. The FE analysis was carried out using ANSY...
